+Project Scope
+-------------
+
+ * Bug fixes and maintenance
+ * Prioritize extensibility and simplicity
+ * Do not make the codebase more complex, keep it simple to hack on
+ * Do not add extra dependency (if we do, add compile time switch to disable it)
+ * New features may be added if it cannot be achieved (easily) via a shell script,
+ doesn't break backwards compatibility and doesn't violate any of the above rules.
+
+Note: Since we aim to be a drop-in replacement for sxiv, we intend to keep all
+sxiv's behaviors/features even in cases where removing them would make the
+code-base simpler.
+
+
+Contribution Guideline
+----------------------
+
+When contributing, make sure:
+
+ * Your contribution falls under nsxiv's scope and aim
+ * You follow the existing code style (see [.editorconfig](.editorconfig))
+ * You open the pull request from a new branch, not from master
+ * To avoid using force pushes, especially for bigger patches. Only use them
+ when there's merge conflicts.
+
+If your contribution is not suitable for general use, it will not be included in nsxiv.
+For changes that are very much up to preference, such as changing values in config.h,
+please do not open a pull request unless you have an objective explanation.
+
+See the [open issues](https://github.com/nsxiv/nsxiv/issues) to find something
+to work on. You can also filter the issues via label:
+
+* [Good first issue](https://github.com/nsxiv/nsxiv/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22):
+ (Easy) Issues which do not require much if any experience.
+* [Up for grabs](https://github.com/nsxiv/nsxiv/issues?q=is%3Aissue+is%3Aopen+label%3A%22up+for+grabs%22):
+ (Intermediate) Issues which are free for anyone who wants to pick it up.
+ Might require some experience.
+* [Help wanted](https://github.com/nsxiv/nsxiv/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22):
+ (Intermediate/Experienced) Issues where we require some help.
+
+Development workflow for maintainers
+------------------------------------
+
+If we notice you contributing and/or showing interest in issues/pull requests,
+we may invite you to join the nsxiv org as a member. Being a member simply means
+you will be able to approve, disapprove and merge pull requests.
+
+Our workflow regarding pull requests is the following:
+
+ * Code related changes require two approvals, but documentation related
+ changes (e.g. typo) can be merged with just one.
+ * Always prefer squashing when merging. In the case a PR makes more than one
+ significant change, use the "don't squash" tag and rebase instead.
+ * When merging, make sure the commit message is cleaned up properly so that
+ it reflects the current intention of the PR.
+
+For releases, the process is the following:
+
+ * Tag the release with a "vN" tag, where N is the version number. Also set
+ the commit message and tag description for the release commit to "Release
+ version N". Make sure to use an annotated tag.
+ * Update `VERSION` macro in the `Makefile`.
+ * Update the changelog (`CHANGELOG.md`):
+ * Include link to the release tarball and add the release date.
+ * Document only the changes or fixes between releases. Don't document
+ changes which never made it into a release.
+ * Use the "Changes" section to document behavior changes since the last
+ release, the "Added" section for new features, and the "Fixes" section
+ for fixed bugs or regressions. Include pull request IDs.
+
+For mundane development related talks which don't warrant their own issue, use
+the [general-dev](https://github.com/nsxiv/nsxiv/discussions/119) discussion
+thread.

+ 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.

+
+nsxiv is available on the following distributions/repositories. If you don't see
+your distro listed here, either contact your distro's package maintainer or
+consider packaging it yourself and adding it to the respective community repo.
+
+Repos not tracked by repology:
+
+* Fedora: Enable the copr repo via `dnf copr enable mamg22/nsxiv`.
+
+
+Dependencies
+------------
+
+nsxiv requires the following software to be installed:
+
+ * Imlib2
+ * X11
+
+The following dependencies are optional.
+
+ * inotify : Used for auto-reloading images on change.
+ Disabled via `HAVE_INOTIFY=0`
+ * libXft, freetype2, fontconfig : Used for the status bar.
+ Disabled via `HAVE_LIBFONTS=0`
+ * giflib : Used for animated gif playback.
+ Disabled via `HAVE_LIBGIF=0`.
+ * libexif : Used for auto-orientation and exif thumbnails.
+ Disable via `HAVE_LIBEXIF=0`
+ * libwebp : Used for animated webp playback.
+ (NOTE: animated webp also requires Imlib2 v1.7.5 or above)
+ Disabled via `HAVE_LIBWEBP=0`.
+
+Please make sure to install the corresponding development packages in case that
+you want to build nsxiv on a distribution with separate runtime and development
+packages (e.g. \*-dev on Debian).
+
+
+Building
+--------
+
+nsxiv is built using the commands:
+
+ $ make
+
+You can pass `HAVE_X=0` to `make` to disable an optional dependency.
+For example:
+
+ $ make HAVE_LIBEXIF=0
+
+will disable `libexif` support. Alternatively they can be disabled via editing
+the `Makefile` directly. `OPT_DEP_DEFAULT=0` can be used to disable all
+optional dependencies.
+
+Installing nsxiv:
+
+ # make install
+
+Installing desktop entry:
+
+ # make install-desktop
+
+Installing icons:
+
+ # make install-icon
+
+Installing all of the above:
+
+ # make install-all
+
+Please note, that these requires root privileges.
+By default, nsxiv is installed using the prefix `/usr/local`, so the full path
+of the executable will be `/usr/local/bin/nsxiv`, the `.desktop` entry will be
+`/usr/local/share/applications/nsxiv.desktop` and the icon path will be
+`/usr/local/share/icons/hicolor/{size}/apps/nsxiv.png`.
+
+You can install nsxiv into a directory of your choice by changing this command to:
+
+ $ make PREFIX="/your/dir" install
+
+Example scripts are installed using `EGPREFIX` which defaults to
+`/usr/local/share/doc/nsxiv/examples`. You can change `EGPREFIX` the same way
+you can change `PREFIX` shown above.
+
+The build-time specific settings of nsxiv can be found in the file *config.h*.
+Please check and change them, so that they fit your needs.
+If the file *config.h* does not already exist, then you have to create it with
+the following command:
+
+ $ make config.h
+
+
+Usage
+-----
+
+Please see man page for information on how to use nsxiv. To do so, execute the
+following after the installation:
+
+ $ man nsxiv
+
+

+* Can I pipe images into nsxiv? <br>
+Yes, see [nsxiv-pipe](https://github.com/nsxiv/nsxiv-extra/tree/master/scripts/nsxiv-pipe)
+
+You may also wish to see the [known issues](https://github.com/nsxiv/nsxiv/issues/242).
+
+
+Customization
+-------------
+
+The main method of customizing nsxiv is by setting values for the variables in *config.h*,
+or by using Xresources as explained in the manual. If these options are not sufficient,
+you may implement your own features by following
+[this guide](https://github.com/nsxiv/nsxiv-extra/blob/master/CUSTOMIZATION.md).
+
+Due to our limited [project scope](CONTRIBUTING.md#Project-Scope), certain features or
+customization cannot be merged into nsxiv mainline. Following the spirit of suckless
+software, we host the [nsxiv-extra](https://github.com/nsxiv/nsxiv-extra) repo where users
+are free to submit whatever patches or scripts they wish.
+
+If you think your custom features can be beneficial for the general user base and is within
+our project scope, please submit it as a pull request on this repository, then we *may*
+merge it to mainline.
+
+Description on how to use or submit patches can be found on
+nsxiv-extra's [README](https://github.com/nsxiv/nsxiv-extra).
+
+
+Download
+--------
+
+You can [browse](https://github.com/nsxiv/nsxiv) the source code repository
+on GitHub or get a copy using git with the following command:
+
+ $ git clone https://github.com/nsxiv/nsxiv.git

+Similar projects
+----------------
+
+If nsxiv isn't able to fit your needs, check out the image viewer section of
+**[suckless rocks](https://suckless.org/rocks)** to find other minimal image
+viewers to try out.
+
+Below are a couple other lesser known projects not listed in suckless rocks.
+
+* [MAGE](https://github.com/explosion-mental/mage) :
+ A smaller/more-suckless version of sxiv.
+* [div](https://github.com/TAAPArthur/div) :
+ Minimal and extensive, aimed at C devs willing to build their own features.
+* [mpv-image-viewer](https://github.com/occivink/mpv-image-viewer) :
+ Lua script to turn mpv into an image viewer. Supports thumbnails via
+ [mpv-gallery-view](https://github.com/occivink/mpv-gallery-view).

+img2data
+--------
+
+img2data is a helper program to convert images to binary data for embedding in
+software. The generated data is used in nsxiv to set the window icons.
+
+
+How It Works
+------------
+
+Each given image is compressed using run-length encoding and a data array is
+generated. In these arrays, the four high bits of each byte are the run length
+minus one and the lowest four bits are the data, which are indices for the
+color array.
+
+See `data.gen.h` or the output of img2data for a better understanding.
+
+
+Dependencies
+------------
+
+img2data requires Imlib2 to be installed.
+
+
+Building
+--------
+
+img2data is built using the command:
+
+ $ CC -Wall -std=c89 -pedantic -lImlib2 img2data.c -o img2data
+
+where `CC` is a C compiler such as `gcc`.
+
+
+Usage
+-----
+
+img2data is used as the following:
+
+ $ ./img2data 16x16.png 32x32.png 48x48.png 64x64.png 128x128.png
+
+You may replace or omit any image, but you must have a `data.gen.h` with at
+least 1 image for nsxiv to compile.

+.SH DESCRIPTION
+nsxiv is a simple image viewer for X.
+.P
+It has two modes of operation: image and thumbnail mode. The default is image
+mode, in which only the current image is shown. In thumbnail mode a grid of
+small previews is displayed, making it easy to choose an image to open.
+.P
+Please note, that the fullscreen mode requires an EWMH/NetWM-compliant window
+manager.

+.TP
+Please see xrdb(1) on how to change them.
+.SH WINDOW TITLE
+The window title can be replaced with the output of a user-provided script,
+which is called by nsxiv whenever there's a redraw. The path of this script is
+.I $XDG_CONFIG_HOME/nsxiv/exec/win-title
+and the arguments given to it (where "Optional" arguments might be empty) are:
+.IP $1 4
+resolved absolute path of the current file
+.IP $2 4
+current file number
+.IP $3 4
+total file count
+.IP $4 4
+image width (Optional: Disabled on thumbnails mode)
+.IP $5 4
+image height (Optional: Disabled on thumbnails mode)
+.IP $6 4
+current zoom (Optional: Disabled on thumbnails mode)
+.P
+The term file is used rather than image as nsxiv does not precheck that the
+input files are valid images. Total file count may be different from the actual
+count of valid images.
+.P
+There is also an example script installed together with nsxiv as
+.IR EGPREFIX/win-title .
+.SH STATUS BAR
+The information displayed on the left side of the status bar can be replaced
+with the output of user-provided script.
+.P
+The script that is called by nsxiv whenever an image gets loaded is located at
+.I $XDG_CONFIG_HOME/nsxiv/exec/image-info
+and the arguments given to it are:
+.IP $1 4
+path to image file (as provided by the user)
+.IP $2 4
+image width
+.IP $3 4
+image height
+.IP $4 4
+fully resolved path to the image file
+.P
+In thumbnail mode, the script that is called is located at
+.I $XDG_CONFIG_HOME/nsxiv/exec/thumb-info
+and the arguments given to it are:
+.IP $1 4
+path to image file (as provided by the user)
+.IP $2 4
+empty
+.IP $3 4
+empty
+.IP $4 4
+fully resolved path to the image file
+.P
+There are also example scripts installed together with nsxiv as
+.IR EGPREFIX/image-info
+and
+.IR EGPREFIX/thumb-info .
+.SH EXTERNAL KEY HANDLER
+Additional external keyboard commands can be defined using a handler program
+located in
+.IR $XDG_CONFIG_HOME/nsxiv/exec/key-handler .
+The handler is invoked by pressing
+.BR Ctrl-x .
+The next key combo is passed as its first argument. Passed via stdin are the
+images to act upon: all marked images, if in thumbnail mode and at least one
+image has been marked, otherwise the current image. nsxiv(1) will block until
+the handler terminates. It then checks which images have been modified and
+reloads them.
+
+By default nsxiv(1) will send one image per-line to stdin, however when using
+\-0 the image list will be NULL separated and the environment variable
+"$NSXIV_USING_NULL" will be set to 1.
+
+The key combo argument has the following form: "[C-][M-][S-]KEY",
+where C/M/S indicate Ctrl/Meta(Alt)/Shift modifier states and KEY is the X
+keysym as listed in /usr/include/X11/keysymdef.h without the "XK_" prefix.
+If KEY has an uppercase equivalent, S-KEY is resolved into it. For instance,
+K replaces S-k and Scedilla replaces S-scedilla, but S-Delete is sent as-is.
+
+There is also an example script installed together with nsxiv as
+.IR EGPREFIX/key-handler .
+.SH THUMBNAIL CACHING
+nsxiv stores all thumbnails under
+.IR $XDG_CACHE_HOME/nsxiv/ .
+.P
+Use the command line option
+.I \-c
+to remove all orphaned cache files. Additionally, run the following command
+afterwards inside the cache directory to remove empty subdirectories:
+.P
+.RS
+find . \-depth \-type d \-empty ! \-name '.' \-exec rmdir {} \\;
