-                    GNU GENERAL PUBLIC LICENSE
-                       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  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
-this service 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 make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  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.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-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
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the 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 a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-                            NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE 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.
-
-                     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
-convey 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 2 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, write to the Free Software Foundation, Inc.,
-    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision 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, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This 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.

-cgit - CGI for Git
-==================
-
-This is an attempt to create a fast web interface for the Git SCM, using a
-built-in cache to decrease server I/O pressure.
-
-Installation
-------------
-
-Building cgit involves building a proper version of Git. How to do this
-depends on how you obtained the cgit sources:
-
-a) If you're working in a cloned cgit repository, you first need to
-initialize and update the Git submodule:
-
-    $ git submodule init     # register the Git submodule in .git/config
-    $ $EDITOR .git/config    # if you want to specify a different url for git
-    $ git submodule update   # clone/fetch and checkout correct git version
-
-b) If you're building from a cgit tarball, you can download a proper git
-version like this:
-
-    $ make get-git
-
-When either a) or b) has been performed, you can build and install cgit like
-this:
-
-    $ make
-    $ sudo make install
-
-This will install `cgit.cgi` and `cgit.css` into `/var/www/htdocs/cgit`. You
-can configure this location (and a few other things) by providing a `cgit.conf`
-file (see the Makefile for details).
-
-
-Dependencies
-------------
-
-* libzip
-* libcrypto (OpenSSL)
-* libssl (OpenSSL)
-
-Apache configuration
---------------------
-
-A new `Directory` section must probably be added for cgit, possibly something
-like this:
-
-    <Directory "/var/www/htdocs/cgit/">
-        AllowOverride None
-        Options +ExecCGI
-        Order allow,deny
-        Allow from all
-    </Directory>
-
-
-Runtime configuration
----------------------
-
-The file `/etc/cgitrc` is read by cgit before handling a request. In addition
-to runtime parameters, this file may also contain a list of repositories
-displayed by cgit (see `cgitrc.5.txt` for further details).
-
-The cache
----------
-
-When cgit is invoked it looks for a cache file matching the request and
-returns it to the client. If no such cache file exists (or if it has expired),
-the content for the request is written into the proper cache file before the
-file is returned.
-
-If the cache file has expired but cgit is unable to obtain a lock for it, the
-stale cache file is returned to the client. This is done to favour page
-throughput over page freshness.
-
-The generated content contains the complete response to the client, including
-the HTTP headers `Modified` and `Expires`.
-
-Online presence
----------------
-
-* The cgit homepage is hosted by cgit at <https://git.zx2c4.com/cgit/about/>
-
-* Patches, bug reports, discussions and support should go to the cgit
-  mailing list: <cgit@lists.zx2c4.com>. To sign up, visit
-  <https://lists.zx2c4.com/mailman/listinfo/cgit>

-CGITRC(5)
-========
-
-
-NAME
-----
-cgitrc - runtime configuration for cgit
-
-
-SYNOPSIS
---------
-Cgitrc contains all runtime settings for cgit, including the list of git
-repositories, formatted as a line-separated list of NAME=VALUE pairs. Blank
-lines, and lines starting with '#', are ignored.
-
-
-LOCATION
---------
-The default location of cgitrc, defined at compile time, is /etc/cgitrc. At
-runtime, cgit will consult the environment variable CGIT_CONFIG and, if
-defined, use its value instead.
-
-
-GLOBAL SETTINGS
----------------
-about-filter::
-	Specifies a command which will be invoked to format the content of
-	about pages (both top-level and for each repository). The command will
-	get the content of the about-file on its STDIN, the name of the file
-	as the first argument, and the STDOUT from the command will be
-	included verbatim on the about page. Default value: none. See
-	also: "FILTER API".
-
-agefile::
-	Specifies a path, relative to each repository path, which can be used
-	to specify the date and time of the youngest commit in the repository.
-	The first line in the file is used as input to the "parse_date"
-	function in libgit. Recommended timestamp-format is "yyyy-mm-dd
-	hh:mm:ss". You may want to generate this file from a post-receive
-	hook. Default value: "info/web/last-modified".
-
-auth-filter::
-	Specifies a command that will be invoked for authenticating repository
-	access. Receives quite a few arguments, and data on both stdin and
-	stdout for authentication processing. Details follow later in this
-	document. If no auth-filter is specified, no authentication is
-	performed. Default value: none. See also: "FILTER API".
-
-branch-sort::
-	Flag which, when set to "age", enables date ordering in the branch ref
-	list, and when set to "name" enables ordering by branch name. Default
-	value: "name".
-
-cache-about-ttl::
-	Number which specifies the time-to-live, in minutes, for the cached
-	version of the repository about page. See also: "CACHE". Default
-	value: "15".
-
-cache-dynamic-ttl::
-	Number which specifies the time-to-live, in minutes, for the cached
-	version of repository pages accessed without a fixed SHA1. See also:
-	"CACHE". Default value: "5".
-
-cache-repo-ttl::
-	Number which specifies the time-to-live, in minutes, for the cached
-	version of the repository summary page. See also: "CACHE". Default
-	value: "5".
-
-cache-root::
-	Path used to store the cgit cache entries. Default value:
-	"/var/cache/cgit". See also: "MACRO EXPANSION".
-
-cache-root-ttl::
-	Number which specifies the time-to-live, in minutes, for the cached
-	version of the repository index page. See also: "CACHE". Default
-	value: "5".
-
-cache-scanrc-ttl::
-	Number which specifies the time-to-live, in minutes, for the result
-	of scanning a path for git repositories. See also: "CACHE". Default
-	value: "15".
-
-case-sensitive-sort::
-	Sort items in the repo list case sensitively. Default value: "1".
-	See also: repository-sort, section-sort.
-
-cache-size::
-	The maximum number of entries in the cgit cache. When set to "0",
-	caching is disabled. See also: "CACHE". Default value: "0"
-
-cache-snapshot-ttl::
-	Number which specifies the time-to-live, in minutes, for the cached
-	version of snapshots. See also: "CACHE". Default value: "5".
-
-cache-static-ttl::
-	Number which specifies the time-to-live, in minutes, for the cached
-	version of repository pages accessed with a fixed SHA1. See also:
-	"CACHE". Default value: -1".
-
-clone-prefix::
-	Space-separated list of common prefixes which, when combined with a
-	repository url, generates valid clone urls for the repository. This
-	setting is only used if `repo.clone-url` is unspecified. Default value:
-	none.
-
-clone-url::
-	Space-separated list of clone-url templates. This setting is only
-	used if `repo.clone-url` is unspecified. Default value: none. See
-	also: "MACRO EXPANSION", "FILTER API".
-
-commit-filter::
-	Specifies a command which will be invoked to format commit messages.
-	The command will get the message on its STDIN, and the STDOUT from the
-	command will be included verbatim as the commit message, i.e. this can
-	be used to implement bugtracker integration. Default value: none.
-	See also: "FILTER API".
-
-commit-sort::
-	Flag which, when set to "date", enables strict date ordering in the
-	commit log, and when set to "topo" enables strict topological
-	ordering. If unset, the default ordering of "git log" is used. Default
-	value: unset.
-
-css::
-	Url which specifies the css document to include in all cgit pages.
-	Default value: "/cgit.css".
-
-email-filter::
-	Specifies a command which will be invoked to format names and email
-	address of committers, authors, and taggers, as represented in various
-	places throughout the cgit interface. This command will receive an
-	email address and an origin page string as its command line arguments,
-	and the text to format on STDIN. It is to write the formatted text back
-	out onto STDOUT. Default value: none. See also: "FILTER API".
-
-embedded::
-	Flag which, when set to "1", will make cgit generate a html fragment
-	suitable for embedding in other html pages. Default value: none. See
-	also: "noheader".
-
-enable-blame::
-	Flag which, when set to "1", will allow cgit to provide a "blame" page
-	for files, and will make it generate links to that page in appropriate
-	places. Default value: "0".
-
-enable-commit-graph::
-	Flag which, when set to "1", will make cgit print an ASCII-art commit
-	history graph to the left of the commit messages in the repository
-	log page. Default value: "0".
-
-enable-filter-overrides::
-	Flag which, when set to "1", allows all filter settings to be
-	overridden in repository-specific cgitrc files. Default value: none.
-
-enable-follow-links::
-	Flag which, when set to "1", allows users to follow a file in the log
-	view.  Default value: "0".
-
-enable-git-config::
-	Flag which, when set to "1", will allow cgit to use git config to set
-	any repo specific settings. This option is used in conjunction with
-	"scan-path", and must be defined prior, to augment repo-specific
-	settings. The keys gitweb.owner, gitweb.category, gitweb.description,
-	and gitweb.homepage will map to the cgit keys repo.owner, repo.section,
-	repo.desc, and repo.homepage respectively. All git config keys that begin
-	with "cgit." will be mapped to the corresponding "repo." key in cgit.
-	Default value: "0". See also: scan-path, section-from-path.
-
-enable-http-clone::
-	If set to "1", cgit will act as a dumb HTTP endpoint for git clones.
-	You can add "http://$HTTP_HOST$SCRIPT_NAME/$CGIT_REPO_URL" to clone-url
-	to expose this feature. If you use an alternate way of serving git
-	repositories, you may wish to disable this. Default value: "1".
-
-enable-html-serving::
-	Flag which, when set to "1", will allow the /plain handler to serve
-	mimetype headers that result in the file being treated as HTML by the
-	browser. When set to "0", such file types are returned instead as
-	text/plain or application/octet-stream. Default value: "0". See also:
-	"repo.enable-html-serving".
-
-enable-index-links::
-	Flag which, when set to "1", will make cgit generate extra links for
-	each repo in the repository index (specifically, to the "summary",
-	"commit" and "tree" pages). Default value: "0".
-
-enable-index-owner::
-	Flag which, when set to "1", will make cgit display the owner of
-	each repo in the repository index. Default value: "1".
-
-enable-log-filecount::
-	Flag which, when set to "1", will make cgit print the number of
-	modified files for each commit on the repository log page. Default
-	value: "0".
-
-enable-log-linecount::
-	Flag which, when set to "1", will make cgit print the number of added
-	and removed lines for each commit on the repository log page. Default
-	value: "0".
-
-enable-remote-branches::
-	Flag which, when set to "1", will make cgit display remote branches
-	in the summary and refs views. Default value: "0". See also:
-	"repo.enable-remote-branches".
-
-enable-subject-links::
-	Flag which, when set to "1", will make cgit use the subject of the
-	parent commit as link text when generating links to parent commits
-	in commit view. Default value: "0". See also:
-	"repo.enable-subject-links".
-
-enable-tree-linenumbers::
-	Flag which, when set to "1", will make cgit generate linenumber links
-	for plaintext blobs printed in the tree view. Default value: "1".
-
-favicon::
-	Url used as link to a shortcut icon for cgit. It is suggested to use
-	the value "/favicon.ico" since certain browsers will ignore other
-	values. Default value: none.
-
-footer::
-	The content of the file specified with this option will be included
-	verbatim at the bottom of all pages (i.e. it replaces the standard
-	"generated by..." message. Default value: none.
-
-head-include::
-	The content of the file specified with this option will be included
-	verbatim in the html HEAD section on all pages. Default value: none.
-
-header::
-	The content of the file specified with this option will be included
-	verbatim at the top of all pages. Default value: none.
-
-include::
-	Name of a configfile to include before the rest of the current config-
-	file is parsed. Default value: none. See also: "MACRO EXPANSION".
-
-local-time::
-	Flag which, if set to "1", makes cgit print commit and tag times in the
-	servers timezone. Default value: "0".
-
-logo::
-	Url which specifies the source of an image which will be used as a logo
-	on all cgit pages. Default value: "/cgit.png".
-
-logo-link::
-	Url loaded when clicking on the cgit logo image. If unspecified the
-	calculated url of the repository index page will be used. Default
-	value: none.
-
-max-atom-items::
-	Specifies the number of items to display in atom feeds view. Default
-	value: "10".
-
-max-blob-size::
-	Specifies the maximum size of a blob to display HTML for in KBytes.

-	on the repository index page. Default value: "80".
-
-max-stats::
-	Set the default maximum statistics period. Valid values are "week",
-	"month", "quarter" and "year". If unspecified, statistics are
-	disabled. Default value: none. See also: "repo.max-stats".
-
-mimetype.<ext>::
-	Set the mimetype for the specified filename extension. This is used
-	by the `plain` command when returning blob content.
-
-mimetype-file::
-	Specifies the file to use for automatic mimetype lookup. If specified
-	then this field is used as a fallback when no "mimetype.<ext>" match is
-	found. If unspecified then no such lookup is performed. The typical file
-	to use on a Linux system is /etc/mime.types. The format of the file must
-	comply to:
-	- a comment line is an empty line or a line starting with a hash (#),
-	  optionally preceded by whitespace
-	- a non-comment line starts with the mimetype (like image/png), followed
-	  by one or more file extensions (like jpg), all separated by whitespace
-	Default value: none. See also: "mimetype.<ext>".
-
-module-link::

-	on all pages. Default value: none. See also: "embedded".
-
-owner-filter::
-	Specifies a command which will be invoked to format the Owner
-	column of the main page.  The command will get the owner on STDIN,
-	and the STDOUT from the command will be included verbatim in the
-	table.  This can be used to link to additional context such as an
-	owners home page.  When active this filter is used instead of the
-	default owner query url.  Default value: none.
-	See also: "FILTER API".
-
-project-list::
-	A list of subdirectories inside of scan-path, relative to it, that
-	should loaded as git repositories. This must be defined prior to
-	scan-path. Default value: none. See also: scan-path, "MACRO
-	EXPANSION".
-
-readme::
-	Text which will be used as default value for "repo.readme". Multiple
-	config keys may be specified, and cgit will use the first found file
-	in this list. This is useful in conjunction with scan-path. Default
-	value: none. See also: scan-path, repo.readme.
-
-remove-suffix::
-	If set to "1" and scan-path is enabled, if any repositories are found
-	with a suffix of ".git", this suffix will be removed for the url and
-	name. This must be defined prior to scan-path. Default value: "0".
-	See also: scan-path.
-
-renamelimit::
-	Maximum number of files to consider when detecting renames. The value
-	 "-1" uses the compiletime value in git (for further info, look at
-	  `man git-diff`). Default value: "-1".
-
-repository-sort::
-	The way in which repositories in each section are sorted. Valid values
-	are "name" for sorting by the repo name or "age" for sorting by the
-	most recently updated repository. Default value: "name". See also:
-	section, case-sensitive-sort, section-sort.
-
-robots::
-	Text used as content for the "robots" meta-tag. Default value:
-	"index, nofollow".
-
-root-desc::
-	Text printed below the heading on the repository index page. Default
-	value: "a fast webinterface for the git dscm".
-
-root-readme::
-	The content of the file specified with this option will be included
-	verbatim below the "about" link on the repository index page. Default
-	value: none.
-
-root-title::
-	Text printed as heading on the repository index page. Default value:
-	"Git Repository Browser".
-
-scan-hidden-path::
-	If set to "1" and scan-path is enabled, scan-path will recurse into
-	directories whose name starts with a period ('.'). Otherwise,
-	scan-path will stay away from such directories (considered as
-	"hidden"). Note that this does not apply to the ".git" directory in
-	non-bare repos. This must be defined prior to scan-path.
-	Default value: 0. See also: scan-path.
-
-scan-path::
-	A path which will be scanned for repositories. If caching is enabled,
-	the result will be cached as a cgitrc include-file in the cache
-	directory. If project-list has been defined prior to scan-path,
-	scan-path loads only the directories listed in the file pointed to by
-	project-list. Be advised that only the global settings taken
-	before the scan-path directive will be applied to each repository.
-	Default value: none. See also: cache-scanrc-ttl, project-list,
-	"MACRO EXPANSION".
-
-section::
-	The name of the current repository section - all repositories defined
-	after this option will inherit the current section name. Default value:
-	none.
-
-section-sort::
-	Flag which, when set to "1", will sort the sections on the repository
-	listing by name. Set this flag to "0" if the order in the cgitrc file should
-	be preserved. Default value: "1". See also: section,
-	case-sensitive-sort, repository-sort.
-
-section-from-path::
-	A number which, if defined prior to scan-path, specifies how many
-	path elements from each repo path to use as a default section name.
-	If negative, cgit will discard the specified number of path elements
-	above the repo directory. Default value: "0".
-
-side-by-side-diffs::
-	If set to "1" shows side-by-side diffs instead of unidiffs per
-	default. Default value: "0".
-
-snapshots::
-	Text which specifies the default set of snapshot formats that cgit
-	generates links for. The value is a space-separated list of zero or
-	more of the values "tar", "tar.gz", "tar.bz2", "tar.lz", "tar.xz",
-	"tar.zst" and "zip". The special value "all" enables all snapshot
-	formats. Default value: none.
-	All compressors use default settings. Some settings can be influenced
-	with environment variables, for example set ZSTD_CLEVEL=10 in web
-	server environment for higher (but slower) zstd compression.
-
-source-filter::
-	Specifies a command which will be invoked to format plaintext blobs
-	in the tree view. The command will get the blob content on its STDIN
-	and the name of the blob as its only command line argument. The STDOUT
-	from the command will be included verbatim as the blob contents, i.e.
-	this can be used to implement e.g. syntax highlighting. Default value:
-	none. See also: "FILTER API".
-
-summary-branches::
-	Specifies the number of branches to display in the repository "summary"
-	view. Default value: "10".
-
-summary-log::
-	Specifies the number of log entries to display in the repository
-	"summary" view. Default value: "10".
-
-summary-tags::
-	Specifies the number of tags to display in the repository "summary"
-	view. Default value: "10".
-
-strict-export::
-	Filename which, if specified, needs to be present within the repository
-	for cgit to allow access to that repository. This can be used to emulate
-	gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
-	repositories to match those exported by git-daemon. This option must
-	be defined prior to scan-path.
-
-virtual-root::
-	Url which, if specified, will be used as root for all cgit links. It
-	will also cause cgit to generate 'virtual urls', i.e. urls like
-	'/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
-	value: none.
-	NOTE: cgit has recently learned how to use PATH_INFO to achieve the
-	same kind of virtual urls, so this option will probably be deprecated.
-

-
-REPOSITORY-SPECIFIC CGITRC FILE
--------------------------------
-When the option "scan-path" is used to auto-discover git repositories, cgit
-will try to parse the file "cgitrc" within any found repository. Such a
-repo-specific config file may contain any of the repo-specific options
-described above, except "repo.url" and "repo.path". Additionally, the "filter"
-options are only acknowledged in repo-specific config files when
-"enable-filter-overrides" is set to "1".
-
-Note: the "repo." prefix is dropped from the option names in repo-specific
-config files, e.g. "repo.desc" becomes "desc".
-
-
-FILTER API
-----------
-By default, filters are separate processes that are executed each time they
-are needed.  Alternative technologies may be used by prefixing the filter
-specification with the relevant string; available values are:
-
-'exec:'::
-	The default "one process per filter" mode.
-
-
-Parameters are provided to filters as follows.
-
-about filter::
-	This filter is given a single parameter: the filename of the source
-	file to filter. The filter can use the filename to determine (for
-	example) the type of syntax to follow when formatting the readme file.
-	The about text that is to be filtered is available on standard input
-	and the filtered text is expected on standard output.
-
-auth filter::
-	The authentication filter receives 12 parameters:
-	  - filter action, explained below, which specifies which action the
-	    filter is called for
-	  - http cookie
-	  - http method
-	  - http referer
-	  - http path
-	  - http https flag
-	  - cgit repo
-	  - cgit page
-	  - cgit url
-	  - cgit login url
-	When the filter action is "body", this filter must write to output the
-	HTML for displaying the login form, which POSTs to the login url. When
-	the filter action is "authenticate-cookie", this filter must validate
-	the http cookie and return a 0 if it is invalid or 1 if it is invalid,
-	in the exit code / close function. If the filter action is
-	"authenticate-post", this filter receives POST'd parameters on
-	standard input, and should write a complete CGI response, preferably
-	with a 302 redirect, and write to output one or more "Set-Cookie"
-	HTTP headers, each followed by a newline.
-
-commit filter::
-	This filter is given no arguments. The commit message text that is to
-	be filtered is available on standard input and the filtered text is
-	expected on standard output.
-
-email filter::
-	This filter is given two parameters: the email address of the relevant
-	author and a string indicating the originating page. The filter will
-	then receive the text string to format on standard input and is
-	expected to write to standard output the formatted text to be included
-	in the page.
-
-owner filter::
-	This filter is given no arguments.  The owner text is available on
-	standard input and the filter is expected to write to standard
-	output.  The output is included in the Owner column.
-
-source filter::
-	This filter is given a single parameter: the filename of the source
-	file to filter. The filter can use the filename to determine (for
-	example) the syntax highlighting mode. The contents of the source
-	file that is to be filtered is available on standard input and the
-	filtered contents is expected on standard output.
-
-
-All filters are handed the following environment variables:
-
-- CGIT_REPO_URL (from repo.url)
-- CGIT_REPO_NAME (from repo.name)
-- CGIT_REPO_PATH (from repo.path)
-- CGIT_REPO_OWNER (from repo.owner)
-- CGIT_REPO_DEFBRANCH (from repo.defbranch)
-- CGIT_REPO_SECTION (from repo.section)
-- CGIT_REPO_CLONE_URL (from repo.clone-url)
-
-If a setting is not defined for a repository and the corresponding global
-setting is also not defined (if applicable), then the corresponding
-environment variable will be unset.
-
-
-MACRO EXPANSION
----------------
-The following cgitrc options support a simple macro expansion feature,
-where tokens prefixed with "$" are replaced with the value of a similarly
-named environment variable:
-
-- cache-root
-- include
-- project-list
-- scan-path
-
-Macro expansion will also happen on the content of $CGIT_CONFIG, if
-defined.
-
-One usage of this feature is virtual hosting, which in its simplest form
-can be accomplished by adding the following line to /etc/cgitrc:
-
-	include=/etc/cgitrc.d/$HTTP_HOST
-
-The following options are expanded during request processing, and support
-the environment variables defined in "FILTER API":
-
-- clone-url
-- repo.clone-url
-
-
-CACHE
------
-
-All cache ttl values are in minutes. Negative ttl values indicate that a page
-type will never expire, and thus the first time a URL is accessed, the result
-will be cached indefinitely, even if the underlying git repository changes.
-Conversely, when a ttl value is zero, the cache is disabled for that
-particular page type, and the page type is never cached.
-
-SIGNATURES
-----------
-
-Cgit can host .asc signatures corresponding to various snapshot formats,
-through use of git notes. For example, the following command may be used to
-add a signature to a .tar.xz archive:
-
-    git notes --ref=refs/notes/signatures/tar.xz add -C "$(
-	gpg --output - --armor --detach-sign cgit-1.1.tar.xz |
-	git hash-object -w --stdin
-    )" v1.1
-
-If it is instead desirable to attach a signature of the underlying .tar, this
-will be linked, as a special case, beside a .tar.* link that does not have its
-own signature. For example, a signature of a tarball of the latest tag might
-be added with a similar command:
-
-    tag="$(git describe --abbrev=0)"
-    git notes --ref=refs/notes/signatures/tar add -C "$(
-        git archive --format tar --prefix "cgit-${tag#v}/" "$tag" |
-        gpg --output - --armor --detach-sign |
-        git hash-object -w --stdin
-    )" "$tag"
-
-Since git-archive(1) is expected to produce stable output between versions,
-this allows one to generate a long-term signature of the contents of a given
-tag.
