-This is not completely trivial, as OpenTTD references a lot of strings in

-only references the first entry in the list, and does "+ <var>" to get to the

-# Compiling OpenTTD
-
-## Required/optional libraries
-
-OpenTTD makes use of the following external libraries:
-
-- (encouraged) zlib: (de)compressing of old (0.3.0-1.0.5) savegames, content downloads,
-   heightmaps
-- (encouraged) liblzma: (de)compressing of savegames (1.1.0 and later)
-- (encouraged) libpng: making screenshots and loading heightmaps
-- (optional) liblzo2: (de)compressing of old (pre 0.3.0) savegames
-
-For Linux, the following additional libraries are used (for non-dedicated only):
-
-- libSDL2: hardware access (video, sound, mouse)
-- libfreetype: loading generic fonts and rendering them
-- libfontconfig: searching for fonts, resolving font names to actual fonts
-- libicu: handling of right-to-left scripts (e.g. Arabic and Persian) and
-   natural sorting of strings
-
-OpenTTD does not require any of the libraries to be present, but without
-liblzma you cannot open most recent savegames and without zlib you cannot
-open most older savegames or use the content downloading system.
-
-## Windows
-
-You need Microsoft Visual Studio 2017 or more recent.
-
-You can download the free Visual Studio Community Edition from Microsoft at
-https://visualstudio.microsoft.com/vs/community/.
-
-OpenTTD needs the Platform SDK, if it isn't installed already. This can be
-done during installing Visual Studio, by selecting
-`Visual C++ MFC for x86 and x64` (and possibly
-`Visual C++ ATL for x86 and x64` depending on your version). If not, you
-can get download it as [MS Windows Platform SDK](https://developer.microsoft.com/en-US/windows/downloads/windows-10-sdk).
-
-Install the SDK by following the instructions as given.
-
-Dependencies for OpenTTD on Windows are handled via
-[vcpkg](https://github.com/Microsoft/vcpkg/). First you need to install vcpkg
-by following the `Quick Start` instructions of their
-[README](https://github.com/Microsoft/vcpkg/blob/master/README.md).
-
-After this, you can install the dependencies OpenTTD needs. We advise to use
-the `static` versions, and OpenTTD currently needs the following dependencies:
-
-- liblzma
-- libpng
-- lzo
-- zlib
-
-To install both the x64 (64bit) and x86 (32bit) variants (though only one is necessary), you can use:
-
-```ps
-.\vcpkg install liblzma:x64-windows-static libpng:x64-windows-static lzo:x64-windows-static zlib:x64-windows-static
-.\vcpkg install liblzma:x86-windows-static libpng:x86-windows-static lzo:x86-windows-static zlib:x86-windows-static
-```
-
-You can open the folder (as a CMake project). CMake will be detected, and you can compile from there.
-If libraries are installed but not found, you need to set VCPKG_TARGET_TRIPLET in CMake parameters.
-For Visual Studio 2017 you also need to set CMAKE_TOOLCHAIN_FILE.
-(Typical values are shown in the MSVC project file command line example)
-
-Alternatively, you can create a MSVC project file via CMake. For this
-either download CMake from https://cmake.org/download/ or use the version
-that comes with vcpkg. After that, you can run something similar to this:
-
-```powershell
-mkdir build
-cd build
-cmake.exe .. -G"Visual Studio 16 2019" -DCMAKE_TOOLCHAIN_FILE="<location of vcpkg>\vcpkg\scripts\buildsystems\vcpkg.cmake" -DVCPKG_TARGET_TRIPLET="x64-windows-static"
-```
-
-Change `<location of vcpkg>` to where you have installed vcpkg. After this
-in the build folder are MSVC project files. MSVC can rebuild the project
-files himself via the `ZERO_CHECK` project.
-
-## All other platforms
-Minimum required version of CMake is 3.9.
-By default this produces a Debug build with assertations enabled.
-This is a far slower build than release builds.
-
-```bash
-mkdir build
-cd build
-cmake ..
-make
-```
-
-For more information on how to use CMake (including how to make Release builds),
-we urge you to read [their excellent manual](https://cmake.org/cmake/help/latest/guide/user-interaction/index.html).
-
-## CMake Options
-
-Via CMake, several options can be influenced to get different types of
-builds.
-
-- `-DCMAKE_BUILD_TYPE=RelWithDebInfo`: build a release build. This is
-   significant faster than a debug build, but has far less useful information
-   in case of a crash.
-- `-DOPTION_DEDICATED=ON`: build OpenTTD without a GUI. Useful if you are
-   running a headless server, as it requires less libraries to operate.
-- `-DOPTION_USE_ASSERTS=OFF`: disable asserts. Use with care, as assert
-   statements capture early signs of trouble. Release builds have them
-   disabled by default.
-- `-DOPTION_USE_THREADS=OFF`: disable the use of threads. This will block
-   the interface in many places, and in general gives a worse experience of
-   the game. Use with care.
-- `-DOPTION_TOOLS_ONLY=ON`: only build tools like `strgen`. Does not build
-   the game itself. Useful for cross-compiling.
-
-## Supported compilers
-
-Every compiler that is supported by CMake and supports C++17, should be
-able to compile OpenTTD. As the exact list of compilers changes constantly,
-we refer to the compiler manual to see if it supports C++17, and to CMake
-to see if it supports your compiler.
-
-## Compilation of base sets
-
-To recompile the extra graphics needed to play with the original Transport
-Tycoon Deluxe graphics you need GRFCodec (which includes NFORenum) as well.
-GRFCodec can be found at
-https://www.openttd.org/downloads/grfcodec-releases/latest.html.
-
-Having GRFCodec installed can cause regeneration of the `.grf` files, which
-are written in the source directory. This can leave your repository in a
-modified state, as different GRFCodec versions can cause binary differences
-in the resulting `.grf` files. Also translations might have been added for
-the base sets which are not yet included in the base set information files.
-To avoid this behaviour, disable GRFCodec (and NFORenum) in CMake cache
-(`GRFCODEC_EXECUTABLE` and `NFORENUM_EXECUTABLE`).
-
-## Developers settings
-
-You can control some flags directly via `CXXFLAGS` (any combination
-of these flags will work fine too):
-
-- `-DRANDOM_DEBUG`: this helps with debugging desyncs.
-- `-fno-inline`: this avoids creating inline functions; this can make
-  debugging a lot easier.
-- `-O0`: this disables all optimizations; this can make debugging a
-  lot easier.
-- `-p`: this enables profiling.
-
-Always use a clean buildfolder if you changing `CXXFLAGS`, as this
-value is otherwise cached. Example use:
-
-`CXXFLAGS="-fno-inline" cmake ..`

-* Please **do not** open issues or pull requests regarding add-on content in NewGRF, GameScripts, AIs, etc.
-These are created by third-parties.  Please try [irc](https://wiki.openttd.org/en/Development/IRC%20channel) or the [forums](https://www.tt-forums.net/) to discuss these.
-
-* Please use [the web translator](https://translator.openttd.org/) to submit corrections and improvements to translations of the game.

-## Bug reports
-
-A bug is a _demonstrable problem_ that is caused by the code in the repository.
-Good bug reports are extremely helpful, so thanks!
-
-Guidelines for bug reports:
-
-0. Please don't report issues with games where you changed NewGRFs mid-game. (This can be verified with the `gamelog` console command in-game.)
-
-1. Please don't report issues with modified versions of OpenTTD (patchpacks, unofficial ports, and similar).
-
-2. **Use the GitHub issue search** — check if the issue has already been
-reported.
-
-3. **Check if the issue has been fixed** — try to reproduce it using the latest `nightly` build of OpenTTD, available from https://www.openttd.org
-
-4. **Isolate the problem** — ideally create reproducible steps with an attached savegame and screenshots. Try to use few or no NewGRFs, AIs etc if possible.
-
-A good bug report shouldn't leave others needing to chase you up for more information.
-Please try to be as detailed as possible in your report.
-
-* What is your environment?
-* What steps will reproduce the issue?
-* Which operating system(s) experience the problem?
-* What would you expect to be the outcome?
-
-All these details will help people to fix any potential bugs.
-
-Example:
-
-> Short and descriptive example bug report title
->
-> A summary of the issue and the OS environment in which it occurs. If
-> suitable, include the steps required to reproduce the bug.
->
-> 1. This is the first step
-> 2. This is the second step
-> 3. Further steps, etc.
->
-> Attached savegame
-> Attached screenshots showing the issue
-> Crashlogs if the bug causes a crash
->
-> Any other information you want to share that is relevant to the issue being
-> reported. This might include the lines of code that you have identified as
-> causing the bug, and potential solutions (and your opinions on their
-> merits).

-## Feature requests
-
-Before opening a feature request, please take a moment to find out whether your idea fits with the [scope and goals](./CONTRIBUTING.md#project-goals) of the project.
-
-It's up to *you* to make a strong case to convince the project's developers of the merits of this feature.
-
-Please provide as much detail and context as possible.
-This means don't request for a solution, but describe the problem you see and how/why you think it should be fixed.
-
-For feature request we have a strict policy.
-
-Keeping issues around with "a good idea" or "not really a bug but we should maybe fix it" turns out to have the reversed effect: nobody looks at it anymore.
-
-Although we really appreciate feedback and ideas, we will close feature requests that we don't expect to fulfill in the next year.
-
-Many of those ideas etc do have a place on the [forums](https://www.tt-forums.net); and if enough people like it, someone will stand up and make it.
-
-It's usually best to discuss on [Discord](https://discord.gg/openttd) before opening a feature request or working on a large feature in a fork.
-Discussion can take time, but it can be productive and avoid disappointment. :)
-
-
-## Pull requests
-
-Good pull requests—patches, improvements, new features—are a fantastic help.
-
-Pull requests should fit with the [goals of the project](./CONTRIBUTING.md#project-goals).
-
-**Please do ask first** before embarking on any significant pull request (e.g. implementing features, refactoring code, porting to a different language), otherwise you risk spending a lot of time working on something that the project's developers might not want to merge into the project.
-
-Every pull request should have a clear scope, with no unrelated commits.
-
-[Code style](https://wiki.openttd.org/en/Development/Coding%20style) must be complied with for pull requests to be accepted; this also includes [commit message format](https://wiki.openttd.org/en/Development/Coding%20style#commit-message).
-
-Adhering to the following process is the best way to get your work included in the project:
-
-1. [Fork](https://help.github.com/fork-a-repo/) the project, clone your fork, and configure the remotes:
-
-```bash
-git clone https://github.com/<your-username>/OpenTTD.git openttd
-git clone https://github.com/OpenTTD/OpenTTD-git-hooks.git openttd_hooks
-cd openttd
-git remote add upstream https://github.com/OpenTTD/OpenTTD.git
-cd .git/hooks
-ln -s ../../../openttd_hooks/hooks/* .
-```
-
-2. If you cloned a while ago, get the latest changes from upstream:
-
-```bash
-git fetch upstream
-```
-
-3. Create a new topic branch (off the main project development branch) to
-contain your feature, change, or fix:
-
-```bash
-git checkout upstream/master -b <topic-branch-name>
-```
-
-4. Commit your changes in logical chunks. Please adhere to these [git commit message guidelines](https://wiki.openttd.org/en/Development/Coding%20style#commit-message) or your code is unlikely to be merged into the main project.
-Use Git's [interactive rebase](https://docs.github.com/en/get-started/using-git/about-git-rebase) feature to tidy up your commits before making them public.
-
-5. Locally rebase the upstream development branch into your topic branch:
-
-```bash
-git fetch upstream
-git rebase upstream/master
-```
-
-6. Push your topic branch up to your fork the first time:
-
-```bash
-git push --set-upstream origin <topic-branch-name>
-```
-
-And any time after that:
-
-```bash
-git push
-```
-
-7. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/) with a clear title and description against the `master` branch.
-
-**IMPORTANT**: By submitting a pull request or patch, you agree to the [License](#license) and the [Privacy Notice](CONTRIBUTING.md#privacy-notice).
-
-
-### Pull request validation
-
-Continuous integration (CI) tools monitor pull requests, and help us identify build and code quality issues.
-
-The results of the CI tests will show on your pull request.
-
-By clicking on Details you can further zoom in; in case of a failure it will show you why it failed.
-In case of success it will report how awesome you were.
-
-Tip: [commit message format](https://wiki.openttd.org/en/Development/Coding%20style#commit-message) is a common reason for pull requests to fail validation.
-
-
-### Are there any development docs?
-
-There is no single source for OpenTTD development docs. It's a complex project with a long history, and multiple APIs.
-
-A good entry point is [Development](https://wiki.openttd.org/en/Development/) on the OpenTTD wiki; this provides links to wiki documentation and other sources.
-
-The GitHub repo also includes some non-comprehensive documentation in [/docs](./docs).
-
-You may also want the guide to [compiling OpenTTD](./COMPILING.md).

-
-## Project goals
-
-### What are the goals of the official branch?
-
-The main goals of the official branch are:
-
-- Stay faithful to the original gameplay from Transport Tycoon Deluxe
-- Improve the user interface
-- Allow extending the gameplay with add-ons / mods via supported content APIs
-- Provide a (relatively) stable core for both players of the official branch, and for authors of add-ons and maintainers of patchpacks
-
-In contrast, extending or altering the gameplay of the base game is not encouraged.
-
-The rationale behind these goals is that people have different opinions about what OpenTTD is and what it should be.
-When it comes to gameplay, there are at least these groups of people:
-
-- *Model railway (mostly singleplayer)*: build "realistic" landscapes, roleplay a world, or even replicate historical scenarios
-- *Economical challenge (mostly singleplayer)*: run a business with economical challenges
-- *Transport challenge (singleplayer or cooperative multiplayer)*: build efficient track layouts with high cargo throughput and tons of vehicles
-- *Competitive speed run (competitive multiplayer)*: maximize some goal in some limited amount of time
-
-When it comes to gameplay features there are at least these groups of interests:
-
-- *Control freak:* micromanagement like conditional orders, refitting and loading etc.
-- *Casual:* automatisation like cargodist, path based signalling etc.
-
-To please everyone, the official branch tries to stay close to the original gameplay; after all, that is what brought everyone here.
-The preferred method to alter and extend the gameplay is via add-ons like NewGRF and GameScripts.
-
-For a long time, the official branch was also open to features which could be enabled/disabled, but the corner-cases that came with some configurations have rendered some parts of the code very complicated.
-Today, new features have to work with all the already existing features, which is not only challenging in corner cases, but also requires spending considerable more work than just "making it work in the game mode that I play".
-
-The preferred method to introduce new gameplay features is to extend the content APIs, supporting ever more add-on content / mods.
-
-This moves conflict-solving away from the codebase to content authors / players.
-It is more accepted for add-ons not working together than the base game not working with certain setting combinations.
-
-In general the game should allow anything that doesn't violate basic rules, but it should warn players if they take potentially dangerous or "stupid" actions.
-
-For example, players are not prevented from starting vehicles without orders, but will receive a warning about vehicles having too few orders.
-This lack of limitation has led to players challenging themselves to create networks where all vehicles have no orders, increasing gameplay possibilities.
-
-### I do not agree with the goals of the official branch, what can I do instead?
-
-Fork!  There is a rich history of experimental patches for OpenTTD.
-
-Many of these will never be accepted for core, but are creative and interesting ways to modify OpenTTD.
-
-Sometimes patches are combined into long-running patchpacks, modified OpenTTD versions which can be downloaded by anyone, or modified OpenTTD clients for dedicated multiplayer servers.
-
-One of the reasons to keep core relatively stable is to make life easier for patch authors and patchpack maintainers where possible.
-
-Patchpack discussions and related topics may be found in community sites such as [TT-Forums development section](https://www.tt-forums.net/viewforum.php?f=33).

-
-We would like to make you aware that contributing to OpenTTD via git will permanently store the name and email address you provide as well as the actual changes and the time and date you made it inside git's version history.
-
-This is inevitable, because it is a main feature of git.
-If you are concerned about your privacy, we strongly recommend to use "Anonymous &lt;anonymous@openttd.org&gt;" as the git commit author. We might refuse anonymous contributions if malicious intent is suspected.
-
-Please note that the contributor identity, once given, is used for copyright verification and to provide proof should a malicious commit be made.
-As such, the [EU GDPR](https://www.eugdpr.org/key-changes.html) "right to be forgotten" does not apply, as this is an overriding legitimate interest.
-
-Please also note that your commit is public and as such will potentially be processed by many third-parties.
-Git's distributed nature makes it impossible to track where exactly your commit, and thus your personal data, will be stored and be processed.
-If you would not like to accept this risk, please do either commit anonymously or refrain from contributing to the OpenTTD project.

+#
+# Usage
+#
+
+# Synopsis:
+#
+# make WITH_ZLIB=1 UNIX=1 MANUAL_CONFIG=1
+#
+# (See below for the list of possible options.)
+#
+# Alternately, you can run make without the MANUAL_CONFIG part. It then
+# generates Makefile.config, where you can customize all the options.
+# However beware that for all subsequent calls the option values from
+# Makefile.config take precedence to the commandline options.
+#
+# (That means that you probably want to either specify the options on command
+# line together with MANUAL_CONFIG=1 or you want to specify no commandline
+# options at all.)
+
+# Targets:
+#
+# Defaults to building binary
+# clean: remove intermediate build files
+# mrproper: remove intermediate files and makefile configuration
+# upgradeconf: add new options to old Makefile.config
+# osx: OS X application
+# release: used by OSX to make a dmg file ready to release
+
+# Options:
+#
+# Summary of OS choice defines
+# WIN32: building on Windows
+# UNIX: building on *nix derivate (Linux, FreeBSD)
+# OSX: building on Mac OS X
+# MORPHOS: building on MorphOS
+# BEOS: building on BeOS
+# SUNOS: building on SunOS (Solaris)
+#
+# Summary of library choice defines
+# WITH_ZLIB: savegames using zlib
+# WITH_PNG: screenshots using PNG
+# WITH_SDL: SDL video driver support
+# WITH_COCOA: Cocoa video driver support
+#
+# Summary of other defines:
+# DEBUG: build in debug mode
+# PROFILE: build in profile mode, disables -s and -fomit-frame-pointer
+# TRANSLATOR: build in translator mode (untranslated strings are prepended by
+#             a <TODO> mark)
+# RELEASE: this will be the released version number. It replaces all places
+#          where it normally would print the revision number
+# MIDI: if set, it will use it as custom path to midi player.
+#       If unset, it will use the hardcoded path in the c code
+#       This can still be overriden by the music.extmidi openttd.cfg option.
+# WITH_DIRECTMUSIC: enable DirectMusic MIDI support
+# WITH_NETWORK: enable networking
+# DEDICATED: allows compilation on UNIX without SDL. Useful for dedicated servers
+# MAX_NUM_AUTOSAVES: sets the number of autosaves the games will make before starting
+#		to overwrite the old ones. If not set, the game will use 16.
+#		NOTE: assign a number, not a string of a number
+#
+# Paths:
+# INSTALL: If not set, the game uses the directory of the binary to
+# store everything (lang, data, gm, save and openttd.cfg), this is the `old' behaviour.
+# In this case, none of the following paths are used, you also should _not_
+# use `make install', but copy the required stuff yourself (or just play out
+# of you source directory, which should work fine).
+# If you want to use `make install' to install the game globally, you should
+# define it _before_ you build the game. If you only define INSTALL when you
+# do `make install', the game won't be able to find it's files (so you should
+# also define all the following paths before building).
+#
+# So, the following paths should be defined if INSTALL is defined.
+# None of these paths have to end with /
+# PREFIX:	Normally /usr/local
+# BINARY_DIR:	The location of the binary, normally games. (Will be prefixed
+#		with $PREFIX)
+# DATA_DIR: 	The location of the data (lang, data, gm and scenario), normally
+#		share/games/openttd. (Will be prefixed with $PREFIX) Note that scenarios
+#		are only put here if USE_HOMEDIR is true, otherwise they are placed in
+#		PERSONAL_DIR/scenario
+# ICON_DIR:   The location of the openttd icon. (Will be prefixed with
+# 	$PREFIX).
+# PERSONAL_DIR:	The directory where openttd.cfg and the save folder will be
+#		stored. You cannot use ~ here, define USE_HOMEDIR for that.
+# USE_HOMEDIR:	If this variable is set, PERSONAL_DIR will be prefixed with
+#		~/ at runtime (the user's homedir)
+# SECOND_DATA_PATH  Use this data dir if a file is not found in the data dir in the data path
+# CUSTOM_LANG_PATH  If this is set, it will use the path given to search for lng files
+#		instead of the lang dir in the data path
+#   NOTE: both SECOND_DATA_PATH and CUSTOM_LANG_PATH uses paths relative to where OTTD is opened
+#
+# DEST_DIR:	make install will use this directory instead of the filesystem
+# 		root to install its files. This should normally not be used by
+# 		ordinary users, currently it is only used for the debian
+# 		packaging. This value should only be set when calling `make
+# 		install' and is not saved in Makefile.config
+#               (Note that DESTDIR is checked if DEST_DIR is not set.)
+#
+# STATIC: link statically
+# CYGWIN: build in Cygwin environment
+# MINGW: build with MingW compiler, link with MingW libraries
+#
+# VERBOSE: show full compiler invocations instead of brief progress messages
+#
+# Special for crosscompiling there are some commands available:
+#
+# UNIVERSAL_BINARY: builds a universal binary for OSX. Make sure you got both PPC and x86 libs. Only works with GCC 4 or newer
+# TRIPLE_BINARY: builds a universal binary with the addition of code optimised for G5 (which means a total of 3 binaries in one file)
+# OTTD_PPC, OTTD_PPC970, OTTD_i386: compile for target architecture.
+#    Multiple flags can be used so OTTD_PPC:=1 OTTD_i386:=1 produces the same result as UNIVERSAL_BINARY
+#
+# JAGUAR: Crosscompiling for OSX 1.2.8 (codenamed Jaguar). Only works if OSX is defined too. Only works with GCC 4 or newer
+#	This can be changed to any PPC version of OSX by changing the ppc flags in Makefile.config
+#
+# ENDIAN_FORCE: forces the endian-check to give a certain result. Can be BE, LE or PREPROCESSOR.
+#	PREPROCESSOR is always used on all OSX targets and will make the preprocessor pick the right endian.
+#	this means that you don't have to think about endianess when compiling for OSX.
+#	Very useful for universal binaries and crosscompilers. Not sure if it works on non OSX targets
+# WINDRES: the location of your windres
+# CC_HOST: the gcc of your localhost if you are making a target that produces incompatible executables
+# CFLAGS_HOST: cflags used for CC_HOST. Make it something if you are getting errors when you try to compi
+#		windows executables on linux. (just: CFLAGS_HOST:='-I' or something)

-
-## 1.0) About
-
-OpenTTD is a transport simulation game based upon the popular game Transport Tycoon Deluxe, written by Chris Sawyer.
-It attempts to mimic the original game as closely as possible while extending it with new features.
-
-OpenTTD is licensed under the GNU General Public License version 2.0, but includes some 3rd party software under different licenses.
-See the section ["Licensing"](#30-licensing) below for details.
-
-## 1.1) Downloading OpenTTD
-
-OpenTTD can be downloaded from the [official OpenTTD website](https://www.openttd.org/).
-
-Both 'stable' and 'nightly' versions are available for download:
-
-- most people should choose the 'stable' version, as this has been more extensively tested
-- the 'nightly' version includes the latest changes and features, but may sometimes be less reliable
-
-OpenTTD is also available for free on [Steam](https://store.steampowered.com/app/1536610/OpenTTD/), [GOG.com](https://www.gog.com/game/openttd), and the [Microsoft Store](https://www.microsoft.com/p/openttd-official/9ncjg5rvrr1c). On some platforms OpenTTD will be available via your OS package manager or a similar service.
-
-
-## 1.2) OpenTTD gameplay manual
-
-OpenTTD has a [community-maintained wiki](https://wiki.openttd.org/), including a gameplay manual and tips.
-
-
-## 1.3) Supported platforms
-
-OpenTTD has been ported to several platforms and operating systems.
-
-The currently supported platforms are:
-
-- Linux (SDL (OpenGL and non-OpenGL))
-- macOS (universal) (Cocoa)
-- Windows (Win32 GDI / OpenGL)
-
-Other platforms may also work (in particular various BSD systems), but we don't actively test or maintain these.
-
-### 1.3.1) Legacy support
-Platforms, languages and compilers change.
-We'll keep support going on old platforms as long as someone is interested in supporting them, except where it means the project can't move forward to keep up with language and compiler features.
-
-We guarantee that every revision of OpenTTD will be able to load savegames from every older revision (excepting where the savegame is corrupt).
-Please report a bug if you find a save that doesn't load.
-
-## 1.4) Installing and running OpenTTD
-
-OpenTTD is usually straightforward to install, but for more help the wiki [includes an installation guide](https://wiki.openttd.org/en/Manual/Installation).
-
-OpenTTD needs some additional graphics and sound files to run.
-
-For some platforms these will be downloaded during the installation process if required.
-
-For some platforms, you will need to refer to [the installation guide](https://wiki.openttd.org/en/Manual/Installation).
-
-
-### 1.4.1) Free graphics and sound files
-
-The free data files, split into OpenGFX for graphics, OpenSFX for sounds and
-OpenMSX for music can be found at:
-
-- https://www.openttd.org/downloads/opengfx-releases/latest for OpenGFX
-- https://www.openttd.org/downloads/opensfx-releases/latest for OpenSFX
-- https://www.openttd.org/downloads/openmsx-releases/latest for OpenMSX
-
-Please follow the readme of these packages about the installation procedure.
-The Windows installer can optionally download and install these packages.

-### 1.4.2) Original Transport Tycoon Deluxe graphics and sound files
-
-If you want to play with the original Transport Tycoon Deluxe data files you have to copy the data files from the CD-ROM into the baseset/ directory.
-It does not matter whether you copy them from the DOS or Windows version of Transport Tycoon Deluxe.
-The Windows install can optionally copy these files.
-
-You need to copy the following files:
-- sample.cat
-- trg1r.grf or TRG1.GRF
-- trgcr.grf or TRGC.GRF
-- trghr.grf or TRGH.GRF
-- trgir.grf or TRGI.GRF
-- trgtr.grf or TRGT.GRF
-
-
-### 1.4.3) Original Transport Tycoon Deluxe music
-
-If you want the Transport Tycoon Deluxe music, copy the appropriate files from the original game into the baseset folder.
-- TTD for Windows: All files in the gm/ folder (gm_tt00.gm up to gm_tt21.gm)
-- TTD for DOS: The GM.CAT file
-- Transport Tycoon Original: The GM.CAT file, but rename it to GM-TTO.CAT
-
-
-## 1.5) Add-on content / mods
-
-OpenTTD features multiple types of add-on content, which modify gameplay in different ways.
-
-Most types of add-on content can be downloaded within OpenTTD via the 'Check Online Content' button in the main menu.
-
-Add-on content can also be installed manually, but that's more complicated; the [OpenTTD wiki](https://wiki.openttd.org/) may offer help with that, or the [OpenTTD directory structure guide](./docs/directory_structure.md).
-
-
-### 1.6) OpenTTD directories
-
-OpenTTD uses its own directory structure to store game data, add-on content etc.
-
-For more information, see the [directory structure guide](./docs/directory_structure.md).
-
-### 1.7) Compiling OpenTTD
-
-If you want to compile OpenTTD from source, instructions can be found in [COMPILING.md](./COMPILING.md).

-FindIconv
----------
-
-This module finds the ``iconv()`` POSIX.1 functions on the system.
-These functions might be provided in the regular C library or externally
-in the form of an additional library.
-
-The following variables are provided to indicate iconv support:
-
-.. variable:: Iconv_FOUND
-
-  Variable indicating if the iconv support was found.
-
-.. variable:: Iconv_INCLUDE_DIRS
-
-  The directories containing the iconv headers.
-
-.. variable:: Iconv_LIBRARIES
-
-  The iconv libraries to be linked.
-
-.. variable:: Iconv_IS_BUILT_IN
-
-  A variable indicating whether iconv support is stemming from the
-  C library or not. Even if the C library provides `iconv()`, the presence of
-  an external `libiconv` implementation might lead to this being false.
-
-Additionally, the following :prop_tgt:`IMPORTED` target is being provided:
-
-.. variable:: Iconv::Iconv
-
-  Imported target for using iconv.
-
-The following cache variables may also be set:
-
-.. variable:: Iconv_INCLUDE_DIR
-
-  The directory containing the iconv headers.
-
-.. variable:: Iconv_LIBRARY
-
-  The iconv library (if not implicitly given in the C library).
-
-.. note::
-  On POSIX platforms, iconv might be part of the C library and the cache
-  variables ``Iconv_INCLUDE_DIR`` and ``Iconv_LIBRARY`` might be empty.
