-                    GNU GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program.  If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
-    <program>  Copyright (C) <year>  <name of author>
-    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
-  The GNU General Public License does not permit incorporating your program
-into proprietary programs.  If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.  But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+	Major changes between "less" versions 487 and 530
+
+* Don't output terminal init sequence if using -F and file fits on one screen.
+
+* When using -S, mark truncated lines with a special character.
+  The character can be changed or disabled via the new --rscroll option.
+
+* New command M marks the last line displayed on the screen.
+
+* New command ESC-m removes a line mark.
+
+* Status column (enabled via -J) now shows mark letters.
+
+* Status column shows search matches even if highlighting is disabled via -G.
+
+* A second ESC-u command will clear search match markers in the status column.
+
+* Do same ANSI escape code filtering for tag matching that we do for 
+  searching, to help when viewing syntax-highlighted code.
+  
+* Catch SIGTERM and clean up before exiting.
+
+* Fix bug initializing default charset on Windows.
+
+* Handle keypad ENTER key correctly if it sends something other than newline.
+
+* Fix buffering bug when using stdin with a LESSOPEN pipe.
+
+* On Windows, allow 'u' in -D option to enable underlining.
+
+* On Windows, use underline in sgr mode.
+
+* On Windows, convert UTF-8 to multibyte if console is not UTF-8.
+
+* Update Unicode tables to 2017-03-08.
+
+* Pass-thru Unicode formating chars (Cf type) instead of treating them
+  as binary chars. But treat them as binary if -U is set.
+
+* Fix erroneous binary file warning when UTF-8 file contains ANSI SGR sequences.
+
+* Fix bugs when using LESSOPEN and switching between stdin and other files.
+
+* Fix some bugs handling filenames containing shell metacharacters.
+
+* Fix some memory leaks.
+
+* Allow some debugging environment variables to be set in lesskey file.
+
+* Code improvements:
+  . Use ANSI prototypes in funcs.h declarations.
+  . Fix some const mismatches.
+  . Remove archaic "register" in variable declarations.
+
+======================================================================
+
+	Major changes between "less" versions 481 and 487
+
+* New commands ESC-{ and ESC-} to shift to start/end of displayed lines.
+
+* Make search highlights work correctly when changing caselessness with -i.
+
+* New option -Da in Windows version to enable SGR mode.
+
+* Fix "nothing to search" error when top or bottom line on screen is empty.
+
+* Fix bug when terminal has no "cm" termcap entry.
+
+* Fix incorrect display when entering double-width chars in search string.
+
+* Fix bug in Unicode handling that missed some double width characters.
+
+* Update Unicode database to 9.0.0.
+
+======================================================================
+
+	Major changes between "less" versions 458 and 481
+
+* Don't overwrite history file; just append to it.
+
+* New command ESC-G goes to end of currently buffered data in a pipe.
+
+* Disable history feature when compiled with LESSHISTFILE set to "-".
+
+* In more-compatible mode, make the -p option apply to every file opened,
+  not just the first one.
+
+* In more-compatible mode, change the -e option to work like -E, not -EF.
+
+* Treat multiple CRs before LF are like one CR (all the CRs are hidden).
+
+* Allow "extra" string in lesskey file to append to a multi-char command
+  (like a search pattern), without executing the command.
+
+* Ignore -u/-U setting while viewing help file, so that 
+  underline and bold chars are displayed correctly.
+
+* Improve detection of "binary" files in UTF-8 mode.
+
+* Fix bug with ++ commands.
+
+* Fix bug where prompt was sometimes not displayed with +G.
+
+* Fix possible memory corruption 
+
+* Fix bugs and improve performance in ampersand filtering.
+
+* Automate construction of Unicode tables from Unicode database.
+
+* Allow %% escape sequence in LESSOPEN variable.

-\`configure' configures less 1 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR            user executables [EPREFIX/bin]
-  --sbindir=DIR           system admin executables [EPREFIX/sbin]
-  --libexecdir=DIR        program executables [EPREFIX/libexec]
-  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
-  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
-  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
-  --libdir=DIR            object code libraries [EPREFIX/lib]
-  --includedir=DIR        C header files [PREFIX/include]
-  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
-  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
-  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
-  --infodir=DIR           info documentation [DATAROOTDIR/info]
-  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
-  --mandir=DIR            man documentation [DATAROOTDIR/man]
-  --docdir=DIR            documentation root [DATAROOTDIR/doc/less]
-  --htmldir=DIR           html documentation [DOCDIR]

-Optional Features:
-  --disable-option-checking  ignore unrecognized --enable/--with options
-  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
-  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
-  --disable-largefile     omit support for large files
-
-Optional Packages:
-  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
-  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
-  --with-secure  Compile in secure mode
-  --with-no-float  Do not use floating point
-  --with-regex={auto,gnu,pcre,posix,regcmp,re_comp,regcomp,regcomp-local,none}  Select a regular expression library  auto
-  --with-editor=PROGRAM   use PROGRAM as the default editor vi
-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

-DESCRIPTION
-       Less is a program similar to more (1), but which allows backward  move-
-       ment in the file as well as forward movement.  Also, less does not have
-       to read the entire input file before  starting,  so  with  large  input
-       files  it  starts  up  faster than text editors like vi (1).  Less uses
-       termcap (or terminfo on some systems), so it can run on  a  variety  of
-       terminals.   There is even limited support for hardcopy terminals.  (On
-       a hardcopy terminal, lines which should be printed at the  top  of  the
-       screen are prefixed with a caret.)
-
-       Commands  are based on both more and vi.  Commands may be preceded by a
-       decimal number, called N in the descriptions below.  The number is used
-       by some commands, as indicated.
-
-
-COMMANDS
-       In  the following descriptions, ^X means control-X.  ESC stands for the
-       ESCAPE  key;  for  example  ESC-v  means  the  two  character  sequence
-       "ESCAPE", then "v".
-
-       h or H Help:  display  a  summary of these commands.  If you forget all
-              the other commands, remember this one.
-
-       SPACE or ^V or f or ^F
-              Scroll forward N  lines,  default  one  window  (see  option  -z
-              below).   If  N  is  more  than  the screen size, only the final
-              screenful is displayed.  Warning: some systems use ^V as a  spe-
-              cial literalization character.
-
-       z      Like  SPACE,  but  if  N is specified, it becomes the new window
-              size.
-
-       ESC-SPACE
-              Like SPACE, but scrolls a full screenful,  even  if  it  reaches
-              end-of-file in the process.
-
-       ENTER or RETURN or ^N or e or ^E or j or ^J
-              Scroll  forward N lines, default 1.  The entire N lines are dis-
-              played, even if N is more than the screen size.
-
-       d or ^D
-              Scroll forward N lines, default one half of the screen size.  If
-              N  is specified, it becomes the new default for subsequent d and
-              u commands.
-
-       b or ^B or ESC-v
-              Scroll backward N lines,  default  one  window  (see  option  -z
-              below).   If  N  is  more  than  the screen size, only the final
-              screenful is displayed.
-
-       w      Like ESC-v, but if N is specified, it  becomes  the  new  window
-              size.
-
-       y or ^Y or ^P or k or ^K
-              Scroll backward N lines, default 1.  The entire N lines are dis-
-              played, even if N is more than the screen size.   Warning:  some
-              systems use ^Y as a special job control character.
-
-       u or ^U
-              Scroll  backward  N  lines, default one half of the screen size.
-              If N is specified, it becomes the new default for  subsequent  d
-              and u commands.
-
-       ESC-) or RIGHTARROW
-              Scroll  horizontally right N characters, default half the screen
-              width (see the -# option).  If  a  number  N  is  specified,  it
-              becomes  the  default  for  future RIGHTARROW and LEFTARROW com-
-              mands.  While the text is scrolled, it acts  as  though  the  -S
-              option (chop lines) were in effect.
-
-       ESC-( or LEFTARROW
-              Scroll  horizontally  left N characters, default half the screen
-              width (see the -# option).  If  a  number  N  is  specified,  it
-              becomes  the  default  for  future RIGHTARROW and LEFTARROW com-
-              mands.
-
-       r or ^R or ^L
-              Repaint the screen.
-
-       R      Repaint the screen, discarding any buffered  input.   Useful  if
-              the file is changing while it is being viewed.
-
-       F      Scroll  forward, and keep trying to read when the end of file is
-              reached.  Normally this command would be used  when  already  at
-              the  end of the file.  It is a way to monitor the tail of a file
-              which is growing while it is being  viewed.   (The  behavior  is
-              similar to the "tail -f" command.)
-
-       ESC-F  Like  F,  but  as soon as a line is found which matches the last
-              search pattern, the terminal bell is rung and forward  scrolling
-              stops.
-
-       g or < or ESC-<
-              Go to line N in the file, default 1 (beginning of file).  (Warn-
-              ing: this may be slow if N is large.)
-
-       G or > or ESC->
-              Go to line N in the file, default the end of the  file.   (Warn-
-              ing:  this  may  be slow if N is large, or if N is not specified
-              and standard input, rather than a file, is being read.)
-
-       p or % Go to a position N percent into the file.  N should be between 0
-              and 100, and may contain a decimal point.
-
-       P      Go to the line containing byte offset N in the file.
-
-       {      If a left curly bracket appears in the top line displayed on the
-              screen, the { command  will  go  to  the  matching  right  curly
-              bracket.   The matching right curly bracket is positioned on the
-              bottom line of the screen.  If there is more than one left curly
-              bracket  on  the top line, a number N may be used to specify the
-              N-th bracket on the line.
-
-       }      If a right curly bracket appears in the bottom line displayed on
-              the  screen,  the  }  command will go to the matching left curly
-              bracket.  The matching left curly bracket is positioned  on  the
-              top  line  of the screen.  If there is more than one right curly
-              bracket on the top line, a number N may be used to  specify  the
-              N-th bracket on the line.
-
-       (      Like {, but applies to parentheses rather than curly brackets.
-
-       )      Like }, but applies to parentheses rather than curly brackets.
-
-       [      Like  {, but applies to square brackets rather than curly brack-
-              ets.
-
-       ]      Like }, but applies to square brackets rather than curly  brack-
-              ets.
-
-       ESC-^F Followed  by two characters, acts like {, but uses the two char-
-              acters as open and close brackets, respectively.   For  example,
-              "ESC  ^F < >" could be used to go forward to the > which matches
-              the < in the top displayed line.
-
-       ESC-^B Followed by two characters, acts like }, but uses the two  char-
-              acters  as  open and close brackets, respectively.  For example,
-              "ESC ^B < >" could be used to go backward to the < which matches
-              the > in the bottom displayed line.
-
-       m      Followed  by  any  lowercase  letter, marks the current position
-              with that letter.
-
-       '      (Single quote.)  Followed by any lowercase  letter,  returns  to
-              the position which was previously marked with that letter.  Fol-
-              lowed by another single quote, returns to the position at  which
-              the last "large" movement command was executed.  Followed by a ^
-              or $, jumps to the beginning or end of  the  file  respectively.
-              Marks  are  preserved when a new file is examined, so the ' com-
-              mand can be used to switch between input files.
-
-       ^X^X   Same as single quote.
-
-       /pattern
-              Search forward in the file for the N-th line containing the pat-
-              tern.  N defaults to 1.  The pattern is a regular expression, as
-              recognized by the regular expression library  supplied  by  your
-              system.   The search starts at the first line displayed (but see
-              the -a and -j options, which change this).
-
-              Certain characters are special if entered at  the  beginning  of
-              the  pattern;  they modify the type of search rather than become
-              part of the pattern:
-
-              ^N or !
-                     Search for lines which do NOT match the pattern.
-
-              ^E or *
-                     Search multiple files.  That is, if  the  search  reaches
-                     the  END of the current file without finding a match, the
-                     search continues in the next file  in  the  command  line
-                     list.
-
-              ^F or @
-                     Begin  the  search at the first line of the FIRST file in
-                     the command line list, regardless of  what  is  currently
-                     displayed  on  the screen or the settings of the -a or -j
-                     options.
-
-              ^K     Highlight any text which matches the pattern on the  cur-
-                     rent screen, but don't move to the first match (KEEP cur-
-                     rent position).
-
-              ^R     Don't interpret regular expression  metacharacters;  that
-                     is, do a simple textual comparison.
-
-       ?pattern
-              Search  backward  in  the  file for the N-th line containing the
-              pattern.  The search starts at the line immediately  before  the
-              top line displayed.
-
-              Certain characters are special as in the / command:
-
-              ^N or !
-                     Search for lines which do NOT match the pattern.
-
-              ^E or *
-                     Search  multiple  files.   That is, if the search reaches
-                     the beginning of  the  current  file  without  finding  a
-                     match,  the  search continues in the previous file in the
-                     command line list.
-
-              ^F or @
-                     Begin the search at the last line of the last file in the
-                     command  line  list, regardless of what is currently dis-
-                     played on the screen or the settings  of  the  -a  or  -j
-                     options.
-
-              ^K     As in forward searches.
-
-              ^R     As in forward searches.
-
-       ESC-/pattern
-              Same as "/*".
-
-       ESC-?pattern
-              Same as "?*".
-
-       n      Repeat  previous  search, for N-th line containing the last pat-
-              tern.  If the previous search was modified by ^N, the search  is
-              made  for the N-th line NOT containing the pattern.  If the pre-
-              vious search was modified by ^E, the  search  continues  in  the
-              next  (or  previous)  file if not satisfied in the current file.
-              If the previous search was modified by ^R, the  search  is  done
-              without  using  regular  expressions.  There is no effect if the
-              previous search was modified by ^F or ^K.
-
-       N      Repeat previous search, but in the reverse direction.
-
-       ESC-n  Repeat previous  search,  but  crossing  file  boundaries.   The
-              effect is as if the previous search were modified by *.
-
-       ESC-N  Repeat  previous search, but in the reverse direction and cross-
-              ing file boundaries.
-
-       ESC-u  Undo search highlighting.   Turn  off  highlighting  of  strings
-              matching the current search pattern.  If highlighting is already
-              off because of a previous ESC-u command, turn highlighting  back
-              on.   Any  search  command  will also turn highlighting back on.
-              (Highlighting can also be disabled by toggling the -G option; in
-              that case search commands do not turn highlighting back on.)
-
-       &pattern
-              Display  only  lines which match the pattern; lines which do not
-              match the pattern are not displayed.  If pattern  is  empty  (if
-              you  type  &  immediately  followed  by ENTER), any filtering is
-              turned off, and all lines are displayed.  While filtering is  in
-              effect,  an  ampersand  is  displayed  at  the  beginning of the
-              prompt, as a reminder that some lines in the file may be hidden.
-
-              Certain characters are special as in the / command:
-
-              ^N or !
-                     Display only lines which do NOT match the pattern.
-
-              ^R     Don't interpret regular expression  metacharacters;  that
-                     is, do a simple textual comparison.
-
-       :e [filename]
-              Examine  a  new file.  If the filename is missing, the "current"
-              file (see the :n and :p commands below) from the list  of  files
-              in  the  command line is re-examined.  A percent sign (%) in the
-              filename is replaced by the name of the current file.   A  pound
-              sign  (#)  is  replaced  by  the name of the previously examined
-              file.   However,  two  consecutive  percent  signs  are   simply
-              replaced with a single percent sign.  This allows you to enter a
-              filename that contains a percent sign in the  name.   Similarly,
-              two  consecutive  pound  signs  are replaced with a single pound
-              sign.  The filename is inserted into the command  line  list  of
-              files  so  that it can be seen by subsequent :n and :p commands.
-              If the filename consists of several files, they are all inserted
-              into  the  list  of files and the first one is examined.  If the
-              filename contains one or more spaces, the entire filename should
-              be enclosed in double quotes (also see the -" option).
-
-       ^X^V or E
-              Same  as :e.  Warning: some systems use ^V as a special literal-
-              ization character.  On such systems, you may not be able to  use
-              ^V.
-
-       :n     Examine  the next file (from the list of files given in the com-
-              mand line).  If a number N is specified, the N-th next  file  is
-              examined.
-
-       :p     Examine the previous file in the command line list.  If a number
-              N is specified, the N-th previous file is examined.
-
-       :x     Examine the first file in the command line list.  If a number  N
-              is specified, the N-th file in the list is examined.
-
-       :d     Remove the current file from the list of files.
-
-       t      Go  to the next tag, if there were more than one matches for the
-              current tag.  See the -t option for more details about tags.
-
-       T      Go to the previous tag, if there were more than one matches  for
-              the current tag.
-
-       = or ^G or :f
-              Prints  some  information about the file being viewed, including
-              its name and the line number and byte offset of the bottom  line
-              being  displayed.  If possible, it also prints the length of the
-              file, the number of lines in the file and  the  percent  of  the
-              file above the last displayed line.
-
-       -      Followed  by one of the command line option letters (see OPTIONS
-              below), this will change the setting of that option and print  a
-              message  describing  the  new  setting.   If a ^P (CONTROL-P) is
-              entered immediately after the dash, the setting of the option is
-              changed  but  no message is printed.  If the option letter has a
-              numeric value (such as -b or -h), or a string value (such as  -P
-              or  -t), a new value may be entered after the option letter.  If
-              no new value is entered, a message describing the  current  set-
-              ting is printed and nothing is changed.
-
-       --     Like  the  -  command, but takes a long option name (see OPTIONS
-              below) rather than a single option letter.  You must press ENTER
-              or  RETURN after typing the option name.  A ^P immediately after
-              the second dash suppresses printing of a message describing  the
-              new setting, as in the - command.
-
-       -+     Followed  by  one  of  the command line option letters this will
-              reset the option to its default  setting  and  print  a  message
-              describing  the  new  setting.  (The "-+X" command does the same
-              thing as "-+X" on the command line.)  This  does  not  work  for
-              string-valued options.
-
-       --+    Like  the -+ command, but takes a long option name rather than a
-              single option letter.
-
-       -!     Followed by one of the command line option  letters,  this  will
-              reset  the  option  to the "opposite" of its default setting and
-              print a message describing the new setting.  This does not  work
-              for numeric or string-valued options.
-
-       --!    Like  the -! command, but takes a long option name rather than a
-              single option letter.
-
-       _      (Underscore.)  Followed by one of the command line  option  let-
-              ters,  this  will print a message describing the current setting
-              of that option.  The setting of the option is not changed.
-
-       __     (Double underscore.)  Like the _ (underscore) command, but takes
-              a long option name rather than a single option letter.  You must
-              press ENTER or RETURN after typing the option name.
-
-       +cmd   Causes the specified cmd to be executed each time a new file  is
-              examined.  For example, +G causes less to initially display each
-              file starting at the end rather than the beginning.
-
-       V      Prints the version number of less being run.
-
-       q or Q or :q or :Q or ZZ
-              Exits less.
-
-       The following four commands may or may not be valid, depending on  your
-       particular installation.
-
-       v      Invokes  an  editor  to edit the current file being viewed.  The
-              editor is taken from the environment variable VISUAL if defined,
-              or  EDITOR if VISUAL is not defined, or defaults to "vi" if nei-
-              ther VISUAL nor EDITOR is defined.  See also the  discussion  of
-              LESSEDIT under the section on PROMPTS below.
-
-       ! shell-command
-              Invokes  a shell to run the shell-command given.  A percent sign
-              (%) in the command is replaced by the name of the current  file.
-              A pound sign (#) is replaced by the name of the previously exam-
-              ined file.  "!!" repeats the last shell command.   "!"  with  no
-              shell  command  simply  invokes  a  shell.  On Unix systems, the
-              shell is taken from the environment variable SHELL, or  defaults
-              to  "sh".   On  MS-DOS and OS/2 systems, the shell is the normal
-              command processor.
-
-       | <m> shell-command
-              <m> represents any mark letter.  Pipes a section  of  the  input
-              file  to the given shell command.  The section of the file to be
-              piped is between the first line on the current  screen  and  the
-              position  marked by the letter.  <m> may also be ^ or $ to indi-
-              cate beginning or end of file respectively.  If <m> is . or new-
-              line, the current screen is piped.
-
-       s filename
-              Save  the  input  to  a file.  This only works if the input is a
-              pipe, not an ordinary file.
-
-OPTIONS
-       Command line options are described below.  Most options may be  changed
-       while less is running, via the "-" command.
-
-       Most  options  may be given in one of two forms: either a dash followed
-       by a single letter, or two dashes followed by a long  option  name.   A
-       long  option  name  may  be  abbreviated as long as the abbreviation is
-       unambiguous.  For example, --quit-at-eof may be abbreviated --quit, but
-       not --qui, since both --quit-at-eof and --quiet begin with --qui.  Some
-       long option names are in uppercase, such as --QUIT-AT-EOF, as  distinct
-       from  --quit-at-eof.  Such option names need only have their first let-
-       ter capitalized; the remainder of the name may be in either case.   For
-       example, --Quit-at-eof is equivalent to --QUIT-AT-EOF.
-
-       Options are also taken from the environment variable "LESS".  For exam-
-       ple, to avoid typing "less -options ..." each time less is invoked, you
-       might tell csh:
-
-       setenv LESS "-options"
-
-       or if you use sh:
-
-       LESS="-options"; export LESS
-
-       On  MS-DOS,  you don't need the quotes, but you should replace any per-
-       cent signs in the options string by double percent signs.
-
-       The environment variable is parsed before the command line, so  command
-       line  options  override  the  LESS  environment variable.  If an option
-       appears in the LESS variable, it can be reset to its default  value  on
-       the command line by beginning the command line option with "-+".
-
-       Some  options  like -k or -D require a string to follow the option let-
-       ter.  The string for that option is considered to  end  when  a  dollar
-       sign  ($)  is found.  For example, you can set two -D options on MS-DOS
-       like this:
-
-       LESS="Dn9.1$Ds4.1"
-
-       If the --use-backslash option appears earlier in the  options,  then  a
-       dollar  sign or backslash may be included literally in an option string
-       by preceding it with a backslash.  If the --use-backslash option is not
-       in  effect, then backslashes are not treated specially, and there is no
-       way to include a dollar sign in the option string.
-
-       -? or --help
-              This option displays a summary of the commands accepted by  less
-              (the  same  as  the  h  command).   (Depending on how your shell
-              interprets the question mark, it may be necessary to  quote  the
-              question mark, thus: "-\?".)
-
-       -a or --search-skip-screen
-              By  default,  forward searches start at the top of the displayed
-              screen and backwards searches start at the bottom  of  the  dis-
-              played  screen (except for repeated searches invoked by the n or
-              N commands, which  start  after  or  before  the  "target"  line
-              respectively; see the -j option for more about the target line).
-              The -a option causes forward searches to instead  start  at  the
-              bottom  of  the screen and backward searches to start at the top
-              of the screen, thus skipping all lines displayed on the screen.
-
-       -A or --SEARCH-SKIP-SCREEN
-              Causes all forward searches (not just non-repeated searches)  to
-              start  just  after the target line, and all backward searches to
-              start just before the target line.  Thus, forward searches  will
-              skip part of the displayed screen (from the first line up to and
-              including the target line).  Similarly backwards  searches  will
-              skip the displayed screen from the last line up to and including
-              the target line.  This was the default behavior in less versions
-              prior to 441.
-
-       -bn or --buffers=n
-              Specifies  the  amount  of  buffer  space less will use for each
-              file, in units of kilobytes (1024 bytes).   By  default  64K  of
-              buffer  space  is used for each file (unless the file is a pipe;
-              see the -B option).  The -b  option  specifies  instead  that  n
-              kilobytes of buffer space should be used for each file.  If n is
-              -1, buffer space is unlimited; that is, the entire file  can  be
-              read into memory.
-
-       -B or --auto-buffers
-              By default, when data is read from a pipe, buffers are allocated
-              automatically as needed.  If a large amount of data is read from
-              the  pipe,  this  can cause a large amount of memory to be allo-
-              cated.  The -B option disables this automatic allocation of buf-
-              fers  for pipes, so that only 64K (or the amount of space speci-
-              fied by the -b option) is used for the pipe.  Warning: use of -B
-              can  result  in  erroneous display, since only the most recently
-              viewed part of the piped data is kept  in  memory;  any  earlier
-              data is lost.
-
-       -c or --clear-screen
-              Causes  full  screen  repaints  to  be painted from the top line
-              down.  By default, full screen repaints are  done  by  scrolling
-              from the bottom of the screen.
-
-       -C or --CLEAR-SCREEN
-              Same as -c, for compatibility with older versions of less.
-
-       -d or --dumb
-              The -d option suppresses the error message normally displayed if
-              the terminal is dumb; that is, lacks some important  capability,
-              such as the ability to clear the screen or scroll backward.  The
-              -d option does not otherwise change the behavior of  less  on  a
-              dumb terminal.
-
-       -Dxcolor or --color=xcolor
-              [MS-DOS only] Sets the color of the text displayed.  x is a sin-
-              gle character which selects the type  of  text  whose  color  is
-              being  set: n=normal, s=standout, d=bold, u=underlined, k=blink.
-              color is a pair of numbers separated by  a  period.   The  first
-              number  selects  the foreground color and the second selects the
-              background color of the text.  A single number N is the same  as
-              N.M, where M is the normal background color.
-
-
-       -e or --quit-at-eof
-              Causes  less  to  automatically  exit the second time it reaches
-              end-of-file.  By default, the only way to exit less is  via  the
-              "q" command.
-
-       -E or --QUIT-AT-EOF
-              Causes less to automatically exit the first time it reaches end-
-              of-file.
-
-       -f or --force
-              Forces non-regular files to be opened.  (A non-regular file is a
-              directory  or a device special file.)  Also suppresses the warn-
-              ing message when a binary file is opened.  By default, less will
-              refuse to open non-regular files.  Note that some operating sys-
-              tems will not allow directories to be read, even if -f is set.
-
-       -F or --quit-if-one-screen
-              Causes less to automatically exit if the entire file can be dis-
-              played on the first screen.
-
-       -g or --hilite-search
-              Normally,  less  will highlight ALL strings which match the last
-              search command.  The -g option changes this  behavior  to  high-
-              light  only  the  particular  string which was found by the last
-              search command.  This can cause less to run somewhat faster than
-              the default.
-
-       -G or --HILITE-SEARCH
-              The  -G  option  suppresses all highlighting of strings found by
-              search commands.
-
-       -hn or --max-back-scroll=n
-              Specifies a maximum number of lines to scroll backward.   If  it
-              is necessary to scroll backward more than n lines, the screen is
-              repainted in a forward direction instead.  (If the terminal does
-              not have the ability to scroll backward, -h0 is implied.)
-
-       -i or --ignore-case
-              Causes searches to ignore case; that is, uppercase and lowercase
-              are considered identical.  This option is ignored if any  upper-
-              case  letters appear in the search pattern; in other words, if a
-              pattern contains uppercase letters, then that  search  does  not
-              ignore case.
-
-       -I or --IGNORE-CASE
-              Like  -i,  but searches ignore case even if the pattern contains
-              uppercase letters.
-
-       -jn or --jump-target=n
-              Specifies a line on the screen where the "target" line is to  be
-              positioned.   The  target line is the line specified by any com-
-              mand to search for a pattern, jump to a line number, jump  to  a
-              file percentage or jump to a tag.  The screen line may be speci-
-              fied by a number: the top line on the screen is 1, the  next  is
-              2, and so on.  The number may be negative to specify a line rel-
-              ative to the bottom of the screen: the bottom line on the screen
-              is  -1, the second to the bottom is -2, and so on.  Alternately,
-              the screen line may be specified as a fraction of the height  of
-              the  screen,  starting with a decimal point: .5 is in the middle
-              of the screen, .3 is three tenths down from the first line,  and
-              so  on.  If the line is specified as a fraction, the actual line
-              number is recalculated if the terminal  window  is  resized,  so
-              that  the  target  line remains at the specified fraction of the
-              screen height.  If any form of the -j option  is  used,  forward
-              searches  begin  at  the line immediately after the target line,
-              and backward searches begin at the target line,  unless  changed
-              by  -a or -A.  For example, if "-j4" is used, the target line is
-              the fourth line on the screen, so forward searches begin at  the
-              fifth line on the screen.
-
-       -J or --status-column
-              Displays  a  status  column at the left edge of the screen.  The
-              status column shows the lines that matched the  current  search.
-              The  status  column  is  also  used if the -w or -W option is in
-              effect.
-
-       -kfilename or --lesskey-file=filename
-              Causes less to open and interpret the named file  as  a  lesskey
-              (1) file.  Multiple -k options may be specified.  If the LESSKEY
-              or LESSKEY_SYSTEM environment variable is set, or if  a  lesskey
-              file is found in a standard place (see KEY BINDINGS), it is also
-              used as a lesskey file.
-
-       -K or --quit-on-intr
-              Causes less to exit immediately (with status 2) when  an  inter-
-              rupt  character  (usually  ^C) is typed.  Normally, an interrupt
-              character causes less to stop whatever it is doing and return to
-              its  command  prompt.   Note  that  use  of this option makes it
-              impossible to return to the command prompt from the "F" command.
-
-       -L or --no-lessopen
-              Ignore the LESSOPEN environment variable  (see  the  INPUT  PRE-
-              PROCESSOR  section  below).   This option can be set from within
-              less, but it will apply only to files opened  subsequently,  not
-              to the file which is currently open.
-
-       -m or --long-prompt
-              Causes  less  to  prompt verbosely (like more), with the percent
-              into the file.  By default, less prompts with a colon.
-
-       -M or --LONG-PROMPT
-              Causes less to prompt even more verbosely than more.
-
-       -n or --line-numbers
-              Suppresses line numbers.  The default (to use line numbers)  may
-              cause  less  to run more slowly in some cases, especially with a
-              very large input file.  Suppressing line  numbers  with  the  -n
-              option  will  avoid this problem.  Using line numbers means: the
-              line number will be displayed in the verbose prompt and in the =
-              command,  and the v command will pass the current line number to
-              the editor (see also  the  discussion  of  LESSEDIT  in  PROMPTS
-              below).
-
-       -N or --LINE-NUMBERS
-              Causes  a  line  number to be displayed at the beginning of each
-              line in the display.
-
-       -ofilename or --log-file=filename
-              Causes less to copy its input to the named file as it  is  being
-              viewed.  This applies only when the input file is a pipe, not an
-              ordinary file.  If the file already exists, less  will  ask  for
-              confirmation before overwriting it.
-
-       -Ofilename or --LOG-FILE=filename
-              The -O option is like -o, but it will overwrite an existing file
-              without asking for confirmation.
-
-              If no log file has been specified, the -o and -O options can  be
-              used  from  within  less  to specify a log file.  Without a file
-              name, they will simply report the name of the log file.  The "s"
-              command is equivalent to specifying -o from within less.
-
-       -ppattern or --pattern=pattern
-              The  -p  option  on the command line is equivalent to specifying
-              +/pattern; that is, it tells less to start at the  first  occur-
-              rence of pattern in the file.
-
-       -Pprompt or --prompt=prompt
-              Provides  a  way  to  tailor the three prompt styles to your own
-              preference.  This option would normally be put in the LESS envi-
-              ronment variable, rather than being typed in with each less com-
-              mand.  Such an option must either be the last option in the LESS
-              variable,  or be terminated by a dollar sign.  -Ps followed by a
-              string changes the default (short) prompt to that  string.   -Pm
-              changes  the  medium  (-m)  prompt.   -PM  changes the long (-M)
-              prompt.  -Ph changes  the  prompt  for  the  help  screen.   -P=
-              changes  the  message printed by the = command.  -Pw changes the
-              message printed while waiting for data (in the F command).   All
-              prompt  strings  consist  of  a  sequence of letters and special
-              escape sequences.  See the section on PROMPTS for more details.
-
-       -q or --quiet or --silent
-              Causes moderately "quiet" operation: the terminal  bell  is  not
-              rung if an attempt is made to scroll past the end of the file or
-              before the beginning of the file.  If the terminal has a "visual
-              bell",  it  is  used  instead.  The bell will be rung on certain
-              other errors, such as typing an invalid character.  The  default
-              is to ring the terminal bell in all such cases.
-
-       -Q or --QUIET or --SILENT
-              Causes  totally  "quiet"  operation:  the terminal bell is never
-              rung.
-
-       -r or --raw-control-chars
-              Causes "raw" control characters to be displayed.  The default is
-              to  display  control  characters  using  the caret notation; for
-              example, a control-A (octal 001) is displayed as "^A".  Warning:
-              when the -r option is used, less cannot keep track of the actual
-              appearance of the screen (since this depends on how  the  screen
-              responds to each type of control character).  Thus, various dis-
-              play problems may result, such as long lines being split in  the
-              wrong place.
-
-       -R or --RAW-CONTROL-CHARS
-              Like  -r,  but  only ANSI "color" escape sequences are output in
-              "raw" form.  Unlike -r, the screen appearance is maintained cor-
-              rectly  in  most  cases.   ANSI  "color"  escape  sequences  are
-              sequences of the form:
-
-                   ESC [ ... m
-
-              where the "..." is zero or more color  specification  characters
-              For  the  purpose  of  keeping  track of screen appearance, ANSI
-              color escape sequences are assumed to not move the cursor.   You
-              can  make less think that characters other than "m" can end ANSI
-              color escape  sequences  by  setting  the  environment  variable
-              LESSANSIENDCHARS to the list of characters which can end a color
-              escape sequence.  And you can make less  think  that  characters
-              other  than the standard ones may appear between the ESC and the
-              m by setting the environment variable  LESSANSIMIDCHARS  to  the
-              list of characters which can appear.
-
-       -s or --squeeze-blank-lines
-              Causes  consecutive  blank  lines  to  be squeezed into a single
-              blank line.  This is useful when viewing nroff output.
-
-       -S or --chop-long-lines
-              Causes lines longer than the screen width to be  chopped  (trun-
-              cated) rather than wrapped.  That is, the portion of a long line
-              that does not fit in the screen width is not shown.  The default
-              is  to  wrap  long  lines; that is, display the remainder on the
-              next line.
-
-       -ttag or --tag=tag
-              The -t option, followed immediately by a TAG, will edit the file
-              containing  that tag.  For this to work, tag information must be
-              available; for example, there may  be  a  file  in  the  current
-              directory called "tags", which was previously built by ctags (1)
-              or an equivalent command.  If the environment variable LESSGLOB-
-              ALTAGS  is set, it is taken to be the name of a command compati-
-              ble with global (1), and that command is executed  to  find  the
-              tag.  (See http://www.gnu.org/software/global/global.html).  The
-              -t option may also be specified from within less  (using  the  -
-              command)  as a way of examining a new file.  The command ":t" is
-              equivalent to specifying -t from within less.
-
-       -Ttagsfile or --tag-file=tagsfile
-              Specifies a tags file to be used instead of "tags".
-
-       -u or --underline-special
-              Causes backspaces and carriage returns to be treated  as  print-
-              able  characters;  that  is,  they are sent to the terminal when
-              they appear in the input.
-
-       -U or --UNDERLINE-SPECIAL
-              Causes backspaces, tabs and carriage returns to  be  treated  as
-              control  characters;  that  is, they are handled as specified by
-              the -r option.
-
-              By default, if neither -u nor  -U  is  given,  backspaces  which
-              appear  adjacent  to  an  underscore  character are treated spe-
-              cially: the underlined text is displayed  using  the  terminal's
-              hardware  underlining capability.  Also, backspaces which appear
-              between two identical  characters  are  treated  specially:  the
-              overstruck  text  is printed using the terminal's hardware bold-
-              face capability.  Other backspaces are deleted, along  with  the
-              preceding character.  Carriage returns immediately followed by a
-              newline are deleted.  Other  carriage  returns  are  handled  as
-              specified  by the -r option.  Text which is overstruck or under-
-              lined can be searched for if neither -u nor -U is in effect.
-
-       -V or --version
-              Displays the version number of less.
-
-       -w or --hilite-unread
-              Temporarily highlights the first  "new"  line  after  a  forward
-              movement of a full page.  The first "new" line is the line imme-
-              diately following the line  previously  at  the  bottom  of  the
-              screen.  Also highlights the target line after a g or p command.
-              The highlight is removed at the next command which causes  move-
-              ment.   The  entire line is highlighted, unless the -J option is
-              in effect, in which case only the status column is highlighted.
-
-       -W or --HILITE-UNREAD
-              Like -w, but temporarily highlights the first new line after any
-              forward movement command larger than one line.
-
-       -xn,... or --tabs=n,...
-              Sets  tab  stops.  If only one n is specified, tab stops are set
-              at multiples of n.  If multiple values separated by  commas  are
-              specified,  tab  stops are set at those positions, and then con-
-              tinue with the same spacing  as  the  last  two.   For  example,
-              -x9,17  will  set  tabs  at  positions  9, 17, 25, 33, etc.  The
-              default for n is 8.
-
-       -X or --no-init
-              Disables sending the termcap initialization and deinitialization
-              strings  to  the  terminal.   This is sometimes desirable if the
-              deinitialization string does something unnecessary, like  clear-
-              ing the screen.
-
-       -yn or --max-forw-scroll=n
-              Specifies a maximum number of lines to scroll forward.  If it is
-              necessary to scroll forward more than n  lines,  the  screen  is
-              repainted  instead.   The -c or -C option may be used to repaint
-              from the top of the screen if desired.  By default, any  forward
-              movement causes scrolling.
-
-       -[z]n or --window=n
-              Changes  the  default  scrolling  window  size  to n lines.  The
-              default is one screenful.  The z and w commands can also be used
-              to  change the window size.  The "z" may be omitted for compati-
-              bility with some versions of more.  If the number n is negative,
-              it  indicates  n  lines  less than the current screen size.  For
-              example, if the screen is 24 lines, -z-4 sets the scrolling win-
-              dow  to  20  lines.   If  the screen is resized to 40 lines, the
-              scrolling window automatically changes to 36 lines.
-
-       -"cc or --quotes=cc
-              Changes the filename quoting character.  This may  be  necessary
-              if  you are trying to name a file which contains both spaces and
-              quote characters.  Followed by a single character, this  changes
-              the  quote  character to that character.  Filenames containing a
-              space should then be surrounded by that character rather than by
-              double  quotes.   Followed  by  two characters, changes the open
-              quote to the first character, and the close quote to the  second
-              character.  Filenames containing a space should then be preceded
-              by the open quote character and  followed  by  the  close  quote
-              character.   Note  that  even  after  the  quote  characters are
-              changed, this option remains -" (a dash  followed  by  a  double
-              quote).
-
-       -~ or --tilde
-              Normally lines after end of file are displayed as a single tilde
-              (~).  This option causes lines after end of file to be displayed
-              as blank lines.
-
-       -# or --shift
-              Specifies the default number of positions to scroll horizontally
-              in the RIGHTARROW and LEFTARROW commands.  If the number  speci-
-              fied  is  zero,  it  sets the default number of positions to one
-              half of the screen width.  Alternately, the number may be speci-
-              fied  as  a fraction of the width of the screen, starting with a
-              decimal point: .5 is half of  the  screen  width,  .3  is  three
-              tenths  of the screen width, and so on.  If the number is speci-
-              fied as a fraction, the actual number  of  scroll  positions  is
-              recalculated  if  the  terminal  window  is resized, so that the
-              actual scroll remains at the specified fraction  of  the  screen
-              width.
-
-       --follow-name
-              Normally,  if  the  input  file is renamed while an F command is
-              executing, less will continue to display  the  contents  of  the
-              original  file  despite  its  name  change.  If --follow-name is
-              specified, during an F command less will periodically attempt to
-              reopen the file by name.  If the reopen succeeds and the file is
-              a different file from the original (which means that a new  file
-              has  been  created  with  the  same  name  as  the original (now
-              renamed) file), less will display the contents of that new file.
-
-       --no-keypad
-              Disables sending the keypad initialization and  deinitialization
-              strings to the terminal.  This is sometimes useful if the keypad
-              strings make the numeric keypad behave in an undesirable manner.
-
-       --use-backslash
-              This option changes the interpretations of options which  follow
-              this one.  After the --use-backslash option, any backslash in an
-              option string is removed and the following  character  is  taken
-              literally.   This  allows a dollar sign to be included in option
-              strings.
-
-       --     A command line argument of "--" marks the end  of  option  argu-
-              ments.   Any  arguments  following this are interpreted as file-
-              names.  This can be useful when viewing a file whose name begins
-              with a "-" or "+".
-
-       +      If  a  command  line option begins with +, the remainder of that
-              option is taken to be an initial command to less.  For  example,
-              +G  tells  less  to start at the end of the file rather than the
-              beginning, and +/xyz tells it to start at the  first  occurrence
-              of  "xyz"  in  the file.  As a special case, +<number> acts like
-              +<number>g; that is, it starts the display at the specified line
-              number  (however,  see  the caveat under the "g" command above).
-              If the option starts with ++, the  initial  command  applies  to
-              every  file being viewed, not just the first one.  The + command
-              described previously may also be used to set (or change) an ini-
-              tial command for every file.
-
-
-LINE EDITING
-       When  entering command line at the bottom of the screen (for example, a
-       filename for the :e command, or the pattern for a search command), cer-
-       tain  keys  can  be used to manipulate the command line.  Most commands
-       have an alternate form in [ brackets ] which can be used if a key  does
-       not  exist  on  a  particular keyboard.  (Note that the forms beginning
-       with ESC do not work in some MS-DOS and Windows systems because ESC  is
-       the  line  erase  character.)  Any of these special keys may be entered
-       literally by preceding it with the "literal" character,  either  ^V  or
-       ^A.   A  backslash itself may also be entered literally by entering two
-       backslashes.
-
-       LEFTARROW [ ESC-h ]
-              Move the cursor one space to the left.
-
-       RIGHTARROW [ ESC-l ]
-              Move the cursor one space to the right.
-
-       ^LEFTARROW [ ESC-b or ESC-LEFTARROW ]
-              (That is, CONTROL and LEFTARROW simultaneously.)  Move the  cur-
-              sor one word to the left.
-
-       ^RIGHTARROW [ ESC-w or ESC-RIGHTARROW ]
-              (That is, CONTROL and RIGHTARROW simultaneously.)  Move the cur-
-              sor one word to the right.
-
-       HOME [ ESC-0 ]
-              Move the cursor to the beginning of the line.
-
-       END [ ESC-$ ]
-              Move the cursor to the end of the line.
-
-       BACKSPACE
-              Delete the character to the left of the cursor,  or  cancel  the
-              command if the command line is empty.
-
-       DELETE or [ ESC-x ]
-              Delete the character under the cursor.
-
-       ^BACKSPACE [ ESC-BACKSPACE ]
-              (That  is,  CONTROL  and  BACKSPACE simultaneously.)  Delete the
-              word to the left of the cursor.
-
-       ^DELETE [ ESC-X or ESC-DELETE ]
-              (That is, CONTROL and DELETE simultaneously.)  Delete  the  word
-              under the cursor.
-
-       UPARROW [ ESC-k ]
-              Retrieve  the  previous  command  line.  If you first enter some
-              text and then press UPARROW, it will retrieve the previous  com-
-              mand which begins with that text.
-
-       DOWNARROW [ ESC-j ]
-              Retrieve  the  next  command line.  If you first enter some text
-              and then press DOWNARROW, it  will  retrieve  the  next  command
-              which begins with that text.
-
-       TAB    Complete  the partial filename to the left of the cursor.  If it
-              matches more than one filename, the first match is entered  into
-              the  command  line.   Repeated  TABs  will  cycle thru the other
-              matching filenames.  If the completed filename is a directory, a
-              "/"  is  appended to the filename.  (On MS-DOS systems, a "\" is
-              appended.)  The environment variable LESSSEPARATOR can  be  used
-              to specify a different character to append to a directory name.
-
-       BACKTAB [ ESC-TAB ]
-              Like, TAB, but cycles in the reverse direction thru the matching
-              filenames.
-
-       ^L     Complete the partial filename to the left of the cursor.  If  it
-              matches more than one filename, all matches are entered into the
-              command line (if they fit).
-
-       ^U (Unix and OS/2) or ESC (MS-DOS)
-              Delete the entire command line, or cancel  the  command  if  the
-              command line is empty.  If you have changed your line-kill char-
-              acter in Unix to something other than ^U, that character is used
-              instead of ^U.
-
-       ^G     Delete the entire command line and return to the main prompt.
-
-
-KEY BINDINGS
-       You  may define your own less commands by using the program lesskey (1)
-       to create a lesskey file.  This file specifies a set  of  command  keys
-       and  an  action  associated with each key.  You may also use lesskey to
-       change the line-editing keys (see LINE EDITING), and to set environment
-       variables.   If the environment variable LESSKEY is set, less uses that
-       as the name of the lesskey file.  Otherwise, less looks in  a  standard
-       place  for  the lesskey file: On Unix systems, less looks for a lesskey
-       file called "$HOME/.less".  On MS-DOS and Windows systems,  less  looks
-       for  a lesskey file called "$HOME/_less", and if it is not found there,
-       then looks for a lesskey file called "_less" in any directory specified
-       in  the  PATH  environment variable.  On OS/2 systems, less looks for a
-       lesskey file called "$HOME/less.ini", and if  it  is  not  found,  then
-       looks  for  a lesskey file called "less.ini" in any directory specified
-       in the INIT environment variable, and if it not found there, then looks
-       for  a lesskey file called "less.ini" in any directory specified in the
-       PATH environment variable.   See  the  lesskey  manual  page  for  more
-       details.
-
-       A  system-wide lesskey file may also be set up to provide key bindings.
-       If a key is defined in both a local lesskey file and in the system-wide
-       file,  key bindings in the local file take precedence over those in the
-       system-wide file.  If the environment variable LESSKEY_SYSTEM  is  set,
-       less uses that as the name of the system-wide lesskey file.  Otherwise,
-       less looks in a standard place for the  system-wide  lesskey  file:  On
-       Unix  systems,  the system-wide lesskey file is /usr/local/etc/sysless.
-       (However, if less was built with a  different  sysconf  directory  than
-       /usr/local/etc, that directory is where the sysless file is found.)  On
-       MS-DOS and Windows systems, the system-wide lesskey  file  is  c:\_sys-
-       less.  On OS/2 systems, the system-wide lesskey file is c:\sysless.ini.
-
-
-INPUT PREPROCESSOR
-       You  may  define an "input preprocessor" for less.  Before less opens a
-       file, it first gives your input preprocessor a chance to modify the way
-       the  contents of the file are displayed.  An input preprocessor is sim-
-       ply an executable program (or shell script), which writes the  contents
-       of the file to a different file, called the replacement file.  The con-
-       tents of the replacement file are then displayed in place of  the  con-
-       tents  of the original file.  However, it will appear to the user as if
-       the original file is opened; that is, less will  display  the  original
-       filename as the name of the current file.
-
-       An  input preprocessor receives one command line argument, the original
-       filename, as entered by the user.  It  should  create  the  replacement
-       file,  and when finished, print the name of the replacement file to its
-       standard output.  If the input preprocessor does not output a  replace-
-       ment  filename, less uses the original file, as normal.  The input pre-
-       processor is not called when viewing standard  input.   To  set  up  an
-       input  preprocessor, set the LESSOPEN environment variable to a command
-       line which will invoke your  input  preprocessor.   This  command  line
-       should  include  one  occurrence  of  the  string  "%s",  which will be
-       replaced by  the  filename  when  the  input  preprocessor  command  is
-       invoked.
-
-       When less closes a file opened in such a way, it will call another pro-
-       gram, called the input postprocessor, which  may  perform  any  desired
-       clean-up  action  (such  as  deleting  the  replacement file created by
-       LESSOPEN).  This program receives two command line arguments, the orig-
-       inal  filename  as entered by the user, and the name of the replacement
-       file.  To set up an input postprocessor, set the LESSCLOSE  environment
-       variable  to a command line which will invoke your input postprocessor.
-       It may include two  occurrences  of  the  string  "%s";  the  first  is
-       replaced  with  the  original  name of the file and the second with the
-       name of the replacement file, which was output by LESSOPEN.
-
-       For example, on many Unix systems, these two scripts will allow you  to
-       keep files in compressed format, but still let less view them directly:
-
-       lessopen.sh:
-            #! /bin/sh
-            case "$1" in
-            *.Z) uncompress -
-                 if [ -s /tmp/less.$$ ]; then
-                      echo /tmp/less.$$
-                 else
-                      rm -f /tmp/less.$$
-                 fi
-                 ;;
-            esac
-
-       lessclose.sh:
-            #! /bin/sh
-            rm $2
-
-       To  use these scripts, put them both where they can be executed and set
-       LESSOPEN="lessopen.sh %s",  and  LESSCLOSE="lessclose.sh %s %s".   More
-       complex  LESSOPEN  and LESSCLOSE scripts may be written to accept other
-       types of compressed files, and so on.
-
-       It is also possible to set up an input preprocessor to  pipe  the  file
-       data  directly to less, rather than putting the data into a replacement
-       file.  This avoids the need to decompress the entire file before start-
-       ing to view it.  An input preprocessor that works this way is called an
-       input pipe.  An input pipe, instead of writing the name of  a  replace-
-       ment  file  on  its  standard output, writes the entire contents of the
-       replacement file on its standard output.  If the input  pipe  does  not
-       write  any characters on its standard output, then there is no replace-
-       ment file and less uses the original file, as normal.  To use an  input
-       pipe,  make  the first character in the LESSOPEN environment variable a
-       vertical bar (|) to signify that the input  preprocessor  is  an  input
-       pipe.
-
-       For  example, on many Unix systems, this script will work like the pre-
-       vious example scripts:
-
-       lesspipe.sh:
-            #! /bin/sh
-            case "$1" in
-            *.Z) uncompress -c $1  2>/dev/null
-            *)   exit 1
-                 ;;
-            esac
-            exit $?
-
-       To  use  this  script,  put  it  where  it  can  be  executed  and  set
-       LESSOPEN="|lesspipe.sh %s".
-
-       Note  that  a  preprocessor  cannot output an empty file, since that is
-       interpreted as meaning there is no replacement, and the  original  file
-       is used.  To avoid this, if LESSOPEN starts with two vertical bars, the
-       exit status of the script becomes meaningful.  If the  exit  status  is
-       zero,  the  output  is  considered  to  be replacement text, even if it
-       empty.  If the exit status is nonzero, any output is  ignored  and  the
-       original  file  is  used.   For compatibility with previous versions of
-       less, if LESSOPEN starts with only one vertical bar, the exit status of
-       the preprocessor is ignored.
-
-       When  an input pipe is used, a LESSCLOSE postprocessor can be used, but
-       it is usually not necessary since there is no replacement file to clean
-       up.   In  this  case, the replacement file name passed to the LESSCLOSE
-       postprocessor is "-".
-
-       For compatibility with previous versions of less, the input  preproces-
-       sor or pipe is not used if less is viewing standard input.  However, if
-       the first character of LESSOPEN is a dash (-), the  input  preprocessor
-       is  used  on  standard input as well as other files.  In this case, the
-       dash is not considered to be part  of  the  preprocessor  command.   If
-       standard input is being viewed, the input preprocessor is passed a file
-       name consisting of a single dash.  Similarly, if the first two  charac-
-       ters  of  LESSOPEN  are vertical bar and dash (|-) or two vertical bars
-       and a dash (||-), the input pipe is used on standard input as  well  as
-       other files.  Again, in this case the dash is not considered to be part
-       of the input pipe command.

-
-NATIONAL CHARACTER SETS
-       There are three types of characters in the input file:
-
-       normal characters
-              can be displayed directly to the screen.
-
-       control characters
-              should not be displayed directly, but are expected to  be  found
-              in ordinary text files (such as backspace and tab).
-
-       binary characters
-              should  not  be  displayed  directly  and are not expected to be
-              found in text files.
-
-       A "character set" is simply a description of which characters are to be
-       considered  normal,  control,  and binary.  The LESSCHARSET environment
-       variable may be used to select a character set.   Possible  values  for
-       LESSCHARSET are:
-
-       ascii  BS,  TAB, NL, CR, and formfeed are control characters, all chars
-              with values between 32 and 126 are normal, and  all  others  are
-              binary.
-
-       iso8859
-              Selects  an  ISO 8859 character set.  This is the same as ASCII,
-              except characters between 160 and  255  are  treated  as  normal
-              characters.
-
-       latin1 Same as iso8859.
-
-       latin9 Same as iso8859.
-
-       dos    Selects a character set appropriate for MS-DOS.
-
-       ebcdic Selects an EBCDIC character set.
-
-       IBM-1047
-              Selects  an  EBCDIC  character set used by OS/390 Unix Services.
-              This is the EBCDIC analogue of latin1.  You get similar  results
-              by setting either LESSCHARSET=IBM-1047 or LC_CTYPE=en_US in your
-              environment.
-
-       koi8-r Selects a Russian character set.
-
-       next   Selects a character set appropriate for NeXT computers.
-
-       utf-8  Selects the UTF-8 encoding  of  the  ISO  10646  character  set.
-              UTF-8  is  special  in that it supports multi-byte characters in
-              the input file.  It is the  only  character  set  that  supports
-              multi-byte characters.
-
-       windows
-              Selects  a  character  set appropriate for Microsoft Windows (cp
-              1251).
-
-       In rare cases, it may be desired to tailor less to use a character  set
-       other  than the ones definable by LESSCHARSET.  In this case, the envi-
-       ronment variable LESSCHARDEF can be used to define a character set.  It
-       should be set to a string where each character in the string represents
-       one character in the character set.  The character "." is  used  for  a
-       normal  character, "c" for control, and "b" for binary.  A decimal num-
-       ber may be used for repetition.   For  example,  "bccc4b."  would  mean
-       character  0  is  binary,  1,  2  and  3 are control, 4, 5, 6 and 7 are
-       binary, and 8 is normal.  All characters after the last are taken to be
-       the  same  as  the  last,  so characters 9 through 255 would be normal.
-       (This is an example, and does not necessarily represent any real  char-
-       acter set.)
-
-       This  table  shows the value of LESSCHARDEF which is equivalent to each
-       of the possible values for LESSCHARSET:
-
-            ascii     8bcccbcc18b95.b
-            dos       8bcccbcc12bc5b95.b.
-            ebcdic    5bc6bcc7bcc41b.9b7.9b5.b..8b6.10b6.b9.7b
-                      9.8b8.17b3.3b9.7b9.8b8.6b10.b.b.b.
-            IBM-1047  4cbcbc3b9cbccbccbb4c6bcc5b3cbbc4bc4bccbc
-                      191.b
-            iso8859   8bcccbcc18b95.33b.
-            koi8-r    8bcccbcc18b95.b128.
-            latin1    8bcccbcc18b95.33b.
-            next      8bcccbcc18b95.bb125.bb
-
-       If neither LESSCHARSET nor LESSCHARDEF is set, but any of  the  strings
-       "UTF-8",  "UTF8", "utf-8" or "utf8" is found in the LC_ALL, LC_CTYPE or
-       LANG environment variables, then the default character set is utf-8.
-
-       If that string is not found, but your  system  supports  the  setlocale
-       interface,  less  will  use  setlocale  to determine the character set.
-       setlocale is controlled by setting the  LANG  or  LC_CTYPE  environment
-       variables.
-
-       Finally,  if the setlocale interface is also not available, the default
-       character set is latin1.
-
-       Control and  binary  characters  are  displayed  in  standout  (reverse
-       video).  Each such character is displayed in caret notation if possible
-       (e.g. ^A for control-A).  Caret notation is used only if inverting  the
-       0100 bit results in a normal printable character.  Otherwise, the char-
-       acter is displayed as a hex number in angle brackets.  This format  can
-       be  changed by setting the LESSBINFMT environment variable.  LESSBINFMT
-       may begin with a "*" and one character to select the display attribute:
-       "*k"  is  blinking, "*d" is bold, "*u" is underlined, "*s" is standout,
-       and "*n" is normal.  If LESSBINFMT does not begin with  a  "*",  normal
-       attribute  is  assumed.   The remainder of LESSBINFMT is a string which
-       may include one printf-style escape sequence (a % followed by x, X,  o,
-       d,  etc.).   For  example, if LESSBINFMT is "*u[%x]", binary characters
-       are displayed in underlined hexadecimal surrounded  by  brackets.   The
-       default  if  no  LESSBINFMT  is  specified is "*s<%02X>".  Warning: the
-       result of expanding the character via LESSBINFMT must be less  than  31
-       characters.
-
-       When the character set is utf-8, the LESSUTFBINFMT environment variable
-       acts similarly to LESSBINFMT but it applies to Unicode code points that
-       were  successfully  decoded but are unsuitable for display (e.g., unas-
-       signed code points).  Its default  value  is  "<U+%04lX>".   Note  that
-       LESSUTFBINFMT  and  LESSBINFMT  share  their  display attribute setting
-       ("*x") so specifying one will affect both; LESSUTFBINFMT is read  after
-       LESSBINFMT  so  its  setting,  if any, will have priority.  Problematic
-       octets in a UTF-8 file (octets of a truncated  sequence,  octets  of  a
-       complete  but  non-shortest  form  sequence,  illegal octets, and stray
-       trailing octets) are displayed individually using LESSBINFMT so  as  to
-       facilitate diagnostic of how the UTF-8 file is ill-formed.
-
-
-PROMPTS
-       The  -P option allows you to tailor the prompt to your preference.  The
-       string given to the -P option replaces  the  specified  prompt  string.
-       Certain characters in the string are interpreted specially.  The prompt
-       mechanism is rather complicated to provide flexibility, but  the  ordi-
-       nary  user need not understand the details of constructing personalized
-       prompt strings.
-
-       A percent sign followed by a single character is expanded according  to
-       what the following character is:
-
-       %bX    Replaced  by the byte offset into the current input file.  The b
-              is followed by a single character (shown as X above) which spec-
-              ifies  the line whose byte offset is to be used.  If the charac-
-              ter is a "t", the byte offset of the top line in the display  is
-              used, an "m" means use the middle line, a "b" means use the bot-
-              tom line, a "B" means use the line just after the  bottom  line,
-              and  a  "j"  means use the "target" line, as specified by the -j
-              option.
-
-       %B     Replaced by the size of the current input file.
-
-       %c     Replaced by the column number of the text appearing in the first
-              column of the screen.
-
-       %dX    Replaced  by  the  page number of a line in the input file.  The
-              line to be used is determined by the X, as with the %b option.
-
-       %D     Replaced by the number of pages in the input  file,  or  equiva-
-              lently, the page number of the last line in the input file.
-
-       %E     Replaced  by the name of the editor (from the VISUAL environment
-              variable, or the EDITOR environment variable if  VISUAL  is  not
-              defined).  See the discussion of the LESSEDIT feature below.
-
-       %f     Replaced by the name of the current input file.
-
-       %F     Replaced  by the last component of the name of the current input
-              file.
-
-       %i     Replaced by the index of the current file in the list  of  input
-              files.
-
-       %lX    Replaced  by  the  line number of a line in the input file.  The
-              line to be used is determined by the X, as with the %b option.
-
-       %L     Replaced by the line number of the last line in the input file.
-
-       %m     Replaced by the total number of input files.
-
-       %pX    Replaced by the percent into the current input  file,  based  on
-              byte  offsets.  The line used is determined by the X as with the
-              %b option.
-
-       %PX    Replaced by the percent into the current input  file,  based  on
-              line  numbers.  The line used is determined by the X as with the
-              %b option.
-
-       %s     Same as %B.
-
-       %t     Causes any trailing spaces to be removed.  Usually used  at  the
-              end of the string, but may appear anywhere.
-
-       %x     Replaced by the name of the next input file in the list.
-
-       If any item is unknown (for example, the file size if input is a pipe),
-       a question mark is printed instead.
-
-       The format of the prompt string can be  changed  depending  on  certain
-       conditions.   A  question mark followed by a single character acts like
-       an "IF": depending on the following character, a  condition  is  evalu-
-       ated.   If the condition is true, any characters following the question
-       mark and condition character, up to  a  period,  are  included  in  the
-       prompt.   If  the condition is false, such characters are not included.
-       A colon appearing between the question mark and the period can be  used
-       to establish an "ELSE": any characters between the colon and the period
-       are included in the string if and only if the IF  condition  is  false.
-       Condition characters (which follow a question mark) may be:
-
-       ?a     True if any characters have been included in the prompt so far.
-
-       ?bX    True if the byte offset of the specified line is known.
-
-       ?B     True if the size of current input file is known.
-
-       ?c     True if the text is horizontally shifted (%c is not zero).
-
-       ?dX    True if the page number of the specified line is known.
-
-       ?e     True if at end-of-file.
-
-       ?f     True  if  there is an input filename (that is, if input is not a
-              pipe).
-
-       ?lX    True if the line number of the specified line is known.
-
-       ?L     True if the line number of the last line in the file is known.
-
-       ?m     True if there is more than one input file.
-
-       ?n     True if this is the first prompt in a new input file.
-
-       ?pX    True if the percent into the current input file, based  on  byte
-              offsets, of the specified line is known.
-
-       ?PX    True  if  the percent into the current input file, based on line
-              numbers, of the specified line is known.
-
-       ?s     Same as "?B".
-
-       ?x     True if there is a next input file  (that  is,  if  the  current
-              input file is not the last one).
-
-       Any  characters  other  than  the  special  ones (question mark, colon,
-       period, percent, and backslash) become literally part  of  the  prompt.
-       Any  of  the special characters may be included in the prompt literally
-       by preceding it with a backslash.
-
-       Some examples:
-
-       ?f%f:Standard input.
-
-       This prompt prints the filename, if known; otherwise the string  "Stan-
-       dard input".
-
-       ?f%f .?ltLine %lt:?pt%pt\%:?btByte %bt:-...
-
-       This  prompt  would print the filename, if known.  The filename is fol-
-       lowed by the line number, if known, otherwise  the  percent  if  known,
-       otherwise  the  byte  offset  if  known.  Otherwise, a dash is printed.
-       Notice how each question mark has a matching  period,  and  how  the  %
-       after the %pt is included literally by escaping it with a backslash.
-
-       ?n?f%f .?m(file %i of %m) ..?e(END) ?x- Next\: %x..%t
-
-       This  prints  the  filename if this is the first prompt in a file, fol-
-       lowed by the "file N of N" message if there  is  more  than  one  input
-       file.   Then,  if  we are at end-of-file, the string "(END)" is printed
-       followed by the name of the next file, if there is one.   Finally,  any
-       trailing spaces are truncated.  This is the default prompt.  For refer-
-       ence, here are the defaults for  the  other  two  prompts  (-m  and  -M
-       respectively).   Each  is  broken  into  two lines here for readability
-       only.
-
-       ?n?f%f .?m(file %i of %m) ..?e(END) ?x- Next\: %x.:
-            ?pB%pB\%:byte %bB?s/%s...%t
-
-       ?f%f .?n?m(file %i of %m) ..?ltlines %lt-%lb?L/%L. :
-            byte %bB?s/%s. .?e(END) ?x- Next\: %x.:?pB%pB\%..%t
-
-       And here is the default message produced by the = command:
-
-       ?f%f .?m(file %i of %m) .?ltlines %lt-%lb?L/%L. .
-            byte %bB?s/%s. ?e(END) :?pB%pB\%..%t
-
-       The prompt expansion features are also used for another purpose: if  an
-       environment  variable LESSEDIT is defined, it is used as the command to
-       be executed when the v command is  invoked.   The  LESSEDIT  string  is
-       expanded  in the same way as the prompt strings.  The default value for
-       LESSEDIT is:
-
-            %E ?lm+%lm. %f
-
-       Note that this expands to the editor name, followed by a + and the line
-       number,  followed by the file name.  If your editor does not accept the
-       "+linenumber" syntax, or has other differences  in  invocation  syntax,
-       the LESSEDIT variable can be changed to modify this default.
-
-
-SECURITY
-       When  the  environment  variable LESSSECURE is set to 1, less runs in a
-       "secure" mode.  This means these features are disabled:
-
-              !      the shell command
-
-              |      the pipe command
-
-              :e     the examine command.
-
-              v      the editing command
-
-              s  -o  log files
-
-              -k     use of lesskey files
-
-              -t     use of tags files
-
-                     metacharacters in filenames, such as *
-
-                     filename completion (TAB, ^L)
-
-       Less can also be compiled to be permanently in "secure" mode.
-
-
-COMPATIBILITY WITH MORE
-       If the environment variable LESS_IS_MORE is set to 1, or if the program
-       is  invoked via a file link named "more", less behaves (mostly) in con-
-       formance with the POSIX "more" command specification.   In  this  mode,
-       less behaves differently in these ways:
-
-       The  -e  option  works  differently.  If the -e option is not set, less
-       behaves as if the -E option were set.  If the -e option  is  set,  less
-       behaves as if the -e and -F options were set.
-
-       The  -m  option  works  differently.   If the -m option is not set, the
-       medium prompt is used, and it is prefixed with the  string  "--More--".
-       If the -m option is set, the short prompt is used.
-
-       The  -n  option acts like the -z option.  The normal behavior of the -n

-NAME
-       lessecho - expand metacharacters
-
-SYNOPSIS
-       lessecho [-ox] [-cx] [-pn] [-dn] [-mx] [-nn] [-ex] [-a] file ...
-
-DESCRIPTION
-       lessecho  is a program that simply echos its arguments on standard out-
-       put.  But any metacharacter in the output is preceded  by  an  "escape"
-       character, which by default is a backslash.
-
-OPTIONS
-       A summary of options is included below.
-
-       -ex    Specifies  "x", rather than backslash, to be the escape char for
-              metachars.  If x is "-", no escape char is  used  and  arguments
-              containing metachars are surrounded by quotes instead.
-
-       -ox    Specifies  "x",  rather  than double-quote, to be the open quote
-              character, which is used if the -e- option is specified.
-
-       -cx    Specifies "x" to be the close quote character.
-
-       -pn    Specifies "n" to be the open quote character, as an integer.
-
-       -dn    Specifies "n" to be the close quote character, as an integer.
-
-       -mx    Specifies "x" to be a metachar.  By default, no  characters  are
-              considered metachars.
-
-       -nn    Specifies "n" to be a metachar, as an integer.
-
-       -fn    Specifies  "n"  to be the escape char for metachars, as an inte-
-              ger.
-
-       -a     Specifies that all arguments are to be quoted.  The  default  is
-              that only arguments containing metacharacters are quoted

-
-NAME
-       lesskey - specify key bindings for less

-SYNOPSIS

-       lesskey [--output=output] [--] [input]
-       lesskey -V
-       lesskey --version
-
-DESCRIPTION
-       Lesskey  is  used  to specify a set of key bindings to be used by less.
-       The input file is a text file which describes the key bindings.  If the
-       input  file is "-", standard input is read.  If no input file is speci-
-       fied, a standard filename is used as the name of the input file,  which
-       depends  on  the  system being used: On Unix systems, $HOME/.lesskey is
-       used; on MS-DOS systems, $HOME/_lesskey is used; and  on  OS/2  systems
-       $HOME/lesskey.ini  is used, or $INIT/lesskey.ini if $HOME is undefined.
-       The output file is a binary file which is used by less.  If  no  output
-       file  is  specified,  and  the environment variable LESSKEY is set, the
-       value of LESSKEY is used as the name of the output file.  Otherwise,  a
-       standard filename is used as the name of the output file, which depends
-       on the system being used: On Unix  and  OS-9  systems,  $HOME/.less  is
-       used;  on  MS-DOS  systems,  $HOME/_less  is used; and on OS/2 systems,
-       $HOME/less.ini is used, or $INIT/less.ini if $HOME  is  undefined.   If
-       the output file already exists, lesskey will overwrite it.
-
-       The  -V  or --version option causes lesskey to print its version number
-       and immediately exit.  If -V or --version is present, other options and
-       arguments are ignored.
-
-       The  input  file consists of one or more sections.  Each section starts
-       with a line that identifies the type  of  section.   Possible  sections
-       are:
-
-       #command
-              Defines new command keys.
-
-       #line-edit
-              Defines new line-editing keys.
-
-       #env   Defines environment variables.
-
-       Blank  lines  and  lines which start with a pound sign (#) are ignored,
-       except for the special section header lines.
-
-
-COMMAND SECTION
-       The command section begins with the line
-
-       #command
-
-       If the command section is the first section in the file, this line  may
-       be omitted.  The command section consists of lines of the form:
-
-            string <whitespace> action [extra-string] <newline>
-
-       Whitespace  is  any  sequence  of  one or more spaces and/or tabs.  The
-       string is the command key(s) which invoke the action.  The  string  may
-       be a single command key, or a sequence of up to 15 keys.  The action is
-       the name of the less action, from the list below.   The  characters  in
-       the  string may appear literally, or be prefixed by a caret to indicate
-       a control key.  A backslash followed by one to three octal  digits  may
-       be  used  to  specify a character by its octal value.  A backslash fol-
-       lowed by certain characters specifies input characters as follows:
-
-       \b     BACKSPACE
-
-       \e     ESCAPE
-
-       \n     NEWLINE
-
-       \r     RETURN
-
-       \t     TAB
-
-       \ku    UP ARROW
-
-       \kd    DOWN ARROW
-
-       \kr    RIGHT ARROW
-
-       \kl    LEFT ARROW
-
-       \kU    PAGE UP
-
-       \kD    PAGE DOWN
-
-       \kh    HOME
-
-       \ke    END
-
-       \kx    DELETE
-
-       A backslash followed by any other character indicates that character is
-       to  be taken literally.  Characters which must be preceded by backslash
-       include caret, space, tab and the backslash itself.
-
-       An action may be followed by an "extra" string.  When such a command is
-       entered while running less, the action is performed, and then the extra
-       string is parsed, just as if it were typed in to  less.   This  feature
-       can  be used in certain cases to extend the functionality of a command.
-       For example, see the "{" and ":t" commands in the example  below.   The
-       extra  string  has  a  special meaning for the "quit" action: when less
-       quits, first character of the extra string is used as its exit status.
-
-
-EXAMPLE
-       The following input file describes the set of default command keys used
-       by less:

-
-PRECEDENCE
-       Commands  specified  by  lesskey  take precedence over the default com-
-       mands.  A default command key may be disabled by including  it  in  the
-       input  file  with  the  action  "invalid".  Alternatively, a key may be
-       defined to do nothing by using the action  "noaction".   "noaction"  is
-       similar to "invalid", but less will give an error beep for an "invalid"
-       command, but not for a "noaction" command.  In  addition,  ALL  default
-       commands may be disabled by adding this control line to the input file:
-
-       #stop
-
-       This  will  cause  all  default commands to be ignored.  The #stop line
-       should be the last line in that section of the file.
-
-       Be aware that #stop can be dangerous.  Since all default  commands  are
-       disabled, you must provide sufficient commands before the #stop line to
-       enable all necessary actions.  For example, failure to provide a "quit"
-       command can lead to frustration.
-
-
-LINE EDITING SECTION
-       The line-editing section begins with the line:
-
-       #line-edit
-
-       This  section specifies new key bindings for the line editing commands,
-       in a manner similar to the way key bindings for ordinary  commands  are
-       specified  in  the #command section.  The line-editing section consists
-       of a list of keys and actions, one per line as in the example below.
-
-
-EXAMPLE
-       The following input file describes the set of default line-editing keys
-       used by less:
-
-            #line-edit
-            \t        forw-complete
-            \17       back-complete
-            \e\t      back-complete
-            ^L        expand
-            ^V        literal
-            ^A        literal
-            \el       right
-            \kr       right
-            \eh       left
-            \kl       left
-            \eb       word-left
-            \e\kl     word-left
-            \ew       word-right
-            \e\kr     word-right
-            \ei       insert
-            \ex       delete
-            \kx       delete
-            \eX       word-delete
-            \ekx      word-delete
-            \e\b      word-backspace
-            \e0       home
-            \kh       home
-            \e$       end
-            \ke       end
-            \ek       up
-            \ku       up
-            \ej       down
-            ^G        abort
-
-
-
-LESS ENVIRONMENT VARIABLES
-       The environment variable section begins with the line
-
-       #env
-
-       Following  this  line  is  a  list of environment variable assignments.
-       Each line consists of an environment variable name, an equals sign  (=)
-       and  the value to be assigned to the environment variable.  White space
-       before and after the equals sign is  ignored.   Variables  assigned  in
-       this  way  are visible only to less.  If a variable is specified in the
-       system environment and also in a lesskey file, the value in the lesskey
-       file  takes precedence.  Although the lesskey file can be used to over-
-       ride variables set in the environment, the main  purpose  of  assigning
-       variables  in the lesskey file is simply to have all less configuration
-       information stored in one file.
-
-
-EXAMPLE
-       The following input file sets the -i option whenever less is  run,  and
-       specifies the character set to be "latin1":
-
-            #env
-            LESS = -i
-            LESSCHARSET = latin1
-
-
-
-SEE ALSO
-       less(1)
-
-
-WARNINGS
-       On  MS-DOS and OS/2 systems, certain keys send a sequence of characters
-       which start with a NUL character (0).  This  NUL  character  should  be
-       represented as \340 in a lesskey file.
