+Script to scan the OpenTTD source-tree for STR_ entries that are defined but
+no longer used.
+
+This is not completely trivial, as OpenTTD references a lot of strings in
+relation to another string. The most obvious example of this is a list. OpenTTD
+only references the first entry in the list, and does "+ <var>" to get to the
+correct string.
+
+There are other ways OpenTTD does use relative values. This script tries to
+account for all of them, to give the best approximation we have for "this
+string is unused".

+# 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 ..`

+### 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 everyone brought here.
+The preferred method to alter and extent 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).

-## 2.0) Contacting
+## 1.1) Downloading OpenTTD
 
-The easiest way to contact the OpenTTD team is by submitting bug reports or
-posting comments in our forums. You can also chat with us on IRC (#openttd
-on irc.oftc.net).
+OpenTTD can be downloaded from the [official OpenTTD website](https://www.openttd.org/).
 
-The OpenTTD homepage is https://www.openttd.org.
+Both 'stable' and 'nightly' versions are available for download:
 
-You can also find the OpenTTD forums at
-[https://www.tt-forums.net](https://www.tt-forums.net/viewforum.php?f=55).
+- 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
 
-### 2.1) Reporting bugs
+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.
 
-First of all, check whether the bug is not already known. Do this by looking
-through the file called 'known-bugs.txt' which is distributed with OpenTTD
-like this readme.
 
-For tracking our bugs we are using GitHub's issue tracker. You can find
-the tracker at https://github.com/OpenTTD/OpenTTD/issues. Before actually
-reporting take a look through the already reported bugs there to see if
-the bug is already known. The 'known-bugs.txt' file might be a bit outdated
-at the moment you are reading it as only bugs known before the release
-are documented there. Also look through the recently closed bugs.
+## 1.2) OpenTTD gameplay manual
 
-When you are sure it is not already reported you should:
+OpenTTD has a [community-maintained wiki](https://wiki.openttd.org/), including a gameplay manual and tips.
 
-- Make sure you are running a recent version, i.e. run the latest stable or
-   nightly based on where you found the bug.
-- Make sure you are not running a non-official binary, like a patch pack.
-   When you are playing with a patch pack you should report any bugs to the
-   forum thread related to that patch pack.
-- Make it reproducible for the developers. In other words, create a savegame
-   in which you can reproduce the issue once loaded. It is very useful to give
-   us the crash.dmp, crash.sav, crash.log and crash screenshot which are
-   created on crashes.
-- Check whether the bug is already reported on our bug tracker. This includes
-   searching for recently closed bug reports as the bug might already be fixed.
 
-After you have done all that you can report the bug. Please include the
-following information in your bug report:
+## 1.3) Supported platforms
 
-- OpenTTD version (PLEASE test the latest Git revision/nightly build)
-- Bug details, including instructions how to reproduce it
-- Platform (Windows, Linux, FreeBSD, …) and compiler (including version) if
-   you compiled OpenTTD yourself.
-- The processor architecture of your OS (32-bit Windows, 64-bit Windows,
-   Linux on an ARM, Mac OS X on a PowerPC, etc.)
-- Attach a saved game **and** a screenshot if possible
-- If this bug only occurred recently please note the last version without
-   the bug and the first version including the bug. That way we can fix it
-   quicker by looking at the changes made.
-- Attach crash.dmp, crash.log and crash.sav. These files are usually created
-   next to your openttd.cfg. The crash handler will tell you the location.
+OpenTTD has been ported to several platforms and operating systems.
 
-### 2.2) Reporting desyncs
+The currently supported platforms are:
 
-As desyncs are hard to make reproducible OpenTTD has the ability to log all
-actions done by clients so we can replay the whole game in an effort to make
-desyncs better reproducible. You need to turn this ability on. When turned
-on an automatic savegame will be made once the map has been constructed in
-the 'save/autosave' directory, see OpenTTD directories to know where to find
-this directory. Furthermore the log file 'commands-out.log' will be created
-and all actions will be written to there.
+- Linux (SDL (OpenGL and non-OpenGL))
+- macOS (universal) (Cocoa)
+- Windows (Win32 GDI / OpenGL)
 
-To enable the desync debugging you need to set the debug level for 'desync'
-to at least 1. You do this by starting OpenTTD with '`-d desync=<level>`' as
-parameter or by typing '`debug_level desync=<level>`' in OpenTTD's internal
-console.
-The desync debug levels are:
+Other platforms may also work (in particular various BSD systems), but we don't actively test or maintain these.
 
-- 0: nothing.
-- 1: dumping of commands to 'commands-out.log'.
-- 2: same as 1 plus checking vehicle caches and dumping that too.
-- 3: same as 2 plus monthly saves in autosave.
-- 4 and higher: same as 3
+### 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.
 
-Restarting OpenTTD will overwrite 'commands-out.log'. OpenTTD will not remove
-the savegames (dmp_cmds_*.sav) made by the desync debugging system, so you
-have to occasionally remove them yourself!
+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.
 
-The naming format of the desync savegames is as follows:
-dmp_cmds_XXXXXXXX_YYYYYYYY.sav. The XXXXXXXX is the hexadecimal representation
-of the generation seed of the game and YYYYYYYY is the hexadecimal
-representation of the date of the game. This sorts the savegames by game and
-then by date making it easier to find the right savegames.
+## 1.4) Installing and running OpenTTD
 
-When a desync has occurred with the desync debugging turned on you should file
-a bug report with the following files attached:
+OpenTTD is usually straightforward to install, but for more help the wiki [includes an installation guide](https://wiki.openttd.org/en/Manual/Installation).
 
-- commands-out.log as it contains all the commands that were done
-- the last saved savegame (search for the last line beginning with
-   'save: dmp_cmds_' in commands-out.log). We use this savegame to check
-   whether we can quickly reproduce the desync. Otherwise we will need …
-- the first saved savegame (search for the first line beginning with 'save'
-   where the first part, up to the last underscore '_', is the same). We need
-   this savegame to be able to reproduce the bug when the last savegame is not
-   old enough. If you loaded a scenario or savegame you need to attach that.
-- optionally you can attach the savegames from around 50%, 75%, 85%, 90% and
-   95% of the game's progression. We can use these savegames to speed up the
-   reproduction of the desync, but we should be able to reproduce these
-   savegames based on the first savegame and commands-out.log.
-- in case you use any NewGRFs you should attach the ones you used unless
-   we can easily find them ourselves via bananas or when they are in the
-   #openttdcoop pack.
+OpenTTD needs some additional graphics and sound files to run.
 
-Do NOT remove the dmp_cmds savegames of a desync you have reported until the
-desync has been fixed; if you, by accident, send us the wrong savegames we
-will not be able to reproduce the desync and thus will be unable to fix it.
+For some platforms these will be downloaded during the installation process if required.
 
-## 3.0) Supported platforms
+For some platforms, you will need to refer to [the installation guide](https://wiki.openttd.org/en/Manual/Installation).
 
-OpenTTD has been ported to several platforms and operating systems. It should
-not be very difficult to port it to a new platform. The currently working
-platforms are:
 
-- BeOS (SDL or Allegro)
-- DOS (Allegro)
-- FreeBSD (SDL)
-- Linux (SDL or Allegro)
-- macOS (universal) (Cocoa video and sound drivers)
-- MorphOS (SDL)
-- OpenBSD (SDL)
-- OS/2 (SDL)
-- Windows (Win32 GDI (faster) or SDL or Allegro)
-
-## 4.0) Installing and running OpenTTD
-
-Installing OpenTTD is fairly straightforward. Either you have downloaded an
-archive which you have to extract to a directory where you want OpenTTD to
-be installed, or you have downloaded an installer, which will automatically
-extract OpenTTD in the given directory.
-
-OpenTTD looks in multiple locations to find the required data files (described
-in section 4.2). Installing any 3rd party files into a 'shared' location has
-the advantage that you only need to do this step once, rather than copying the
-data files into all OpenTTD versions you have.
-
-Savegames, screenshots, etc are saved relative to the config file (openttd.cfg)
-currently being used. This means that if you use a config file in one of the
-shared directories, savegames will reside in the save/ directory next to the
-openttd.cfg file there.
-
-If you want savegames and screenshots in the directory where the OpenTTD binary
-resides, simply have your config file in that location. But if you remove this
-config file, savegames will still be in this directory (see notes in
-section 4.2 'OpenTTD directories')
-
-OpenTTD comes without AIs, so if you want to play with AIs you have to download
-them. The easiest way is via the 'Check Online Content' button in the main menu.
-You can select some AIs that you think are compatible with your playing style.
-Another way is manually downloading the AIs from the forum although then you
-need to make sure that you install all the required AI libraries too; they get
-automatically selected (and downloaded) if you get the AIs via the 'Check
-Online Content'. If you do not have an AI but have configured OpenTTD to start
-an AI a message will be shown that the 'dummy' AI has been started.
-
-### 4.1) (Required) 3rd party files
-
-Before you run OpenTTD, you need to put the game's data files into a baseset/
-directory which can be located in various places addressed in the following
-section.
-
-For OpenTTD you need to acquire some third party data files. For this you have
-the choice of using the original Transport Tycoon Deluxe data files or a set
-of free data files.
-
-Do NOT copy files included with OpenTTD into 'shared' directories (explained in
-the following sections) as sooner or later you will run into graphical glitches
-when using other versions of the game.
-

-#### 4.1.4) AIs
-
-If you want AIs use the in-game content downloader. If for some reason that is
-not possible or you want to use an AI that has not been uploaded to the content
-download system download the tar file and place it in the ai/ directory. If the
-AI needs libraries you will have to download those too and put them in the
-ai/library/ directory. All AIs and AI Libraries that have been uploaded to
-the content download system can be found at https://noai.openttd.org/downloads.
-The AIs and libraries can be found their in the form of .tar.gz packages.
-OpenTTD can read inside tar files but it does not extract .tar.gz files by itself.
-
-To figure out which libraries you need for an AI you have to start the AI and
-wait for an error message to pop up. The error message will tell you
-'could not find library "lib-name"'. Download that library and try again.
-
-#### 4.1.5) Game scripts
-
-If you want an extra challenge in OpenTTD you can download so-called game
-scripts via the in-game content downloader. These game scripts have varying
-functionality, though they can generally influence town growth, subsidies, add
-goals to reach or provide a different ranking system.
-
-If you download a game script manually you have to follow the same rules as for
-AIs, except that game scripts are placed in the game/ directory instead of the
-ai/ directory.
-
-### 4.2) OpenTTD directories
-
-OpenTTD uses its own directory to store its required 3rd party base set files
-(see section 4.1 'Required 3rd party files') and non-compulsory extension and
-configuration files. See below for their proper place within this OpenTTD main
-data directory.
-
-The main OpenTTD directories can be found in various locations, depending on
-your operating system:
-
-1. The current working directory (from where you started OpenTTD)
-
-    For non-Windows operating systems OpenTTD will not scan for files in this
-    directory if it is your personal directory, i.e. '~/', or when it is the
-    root directory, i.e. '/'.
-
-2. Your personal directory
-    - Windows:
-        - `C:\My Documents\OpenTTD` (95, 98, ME)
-        - `C:\Documents and Settings\<username>\My Documents\OpenTTD` (2000, XP)
-        - `C:\Users\<username>\Documents\OpenTTD` (Vista, 7, 8.1, 10)
-    - macOS: `~/Documents/OpenTTD`
-    - Linux: `$XDG_DATA_HOME/openttd` which is usually `~/.local/share/openttd`
-       when built with XDG base directory support, otherwise `~/.openttd`
-3. The shared directory
-    - Windows:
-        - `C:\Documents and Settings\All Users\Shared Documents\OpenTTD` (2000, XP)
-        - `C:\Users\Public\Documents\OpenTTD` (Vista, 7, 8.1, 10)
-    - macOS: `/Library/Application Support/OpenTTD`
-    - Linux: not available
-4. The binary directory (where the OpenTTD executable is)
-    - Windows: `C:\Program Files\OpenTTD`
-    - Linux: `/usr/games`
-5. The installation directory (Linux only)
-    - Linux: `/usr/share/games/openttd`
-6. The application bundle (macOS only)
-
-    It includes the OpenTTD files (grf+lng) and it will work as long as they
-    are not touched
-
-Different types of data or extensions go into different subdirectories of the
-chosen main OpenTTD directory:
-
-| data type           | directory         | additional info             |
-| ------------------- | ----------------- | --------------------------- |
-| Config File         | (no subdirectory) |                             |
-| Screenshots         | screenshot        |                             |
-| Base Graphics       | baseset           | (or a subdirectory thereof) |
-| Sound Sets          | baseset           | (or a subdirectory thereof) |
-| NewGRFs             | newgrf            | (or a subdirectory thereof) |
-| 32bpp Sets          | newgrf            | (or a subdirectory thereof) |
-| Music Sets          | baseset           | (or a subdirectory thereof) |
-| AIs                 | ai                | (or a subdirectory thereof) |
-| AI Libraries        | ai/library        | (or a subdirectory thereof) |
-| Game Scripts (GS)   | game              | (or a subdirectory thereof) |
-| GS Libraries        | game/library      | (or a subdirectory thereof) |
-| Savegames           | save              |                             |
-| Automatic Savegames | save/autosave     |                             |
-| Scenarios           | scenario          |                             |
-
-The (automatically created) directory content_download is for OpenTTD's internal
-use and no files should be added to it or its subdirectories manually.
-
-#### Notes:
-
-- Linux in the previous list means .deb, but most paths should be similar for
-   others.
-- The previous search order is also used for NewGRFs and openttd.cfg.
-- If openttd.cfg is not found, then it will be created using the 2, 4, 1, 3,
-   5 order. When built with XDG base directory support, openttd.cfg will be
-   created in $XDG_CONFIG_HOME/openttd which is usually ~/.config/openttd.
-- Savegames will be relative to the config file only if there is no save/
-   directory in paths with higher priority than the config file path, but
-   autosaves and screenshots will always be relative to the config file.
-   Unless the configuration file is in $XDG_CONFIG_HOME/openttd, then all
-   other files will be saved under $XDG_DATA_HOME/openttd.
-
-#### The preferred setup:
-
-Place 3rd party files in shared directory (or in personal directory if you do
-not have write access on shared directory) and have your openttd.cfg config
-file in personal directory (where the game will then also place savegames and
-screenshots).
-
-### 4.3) Portable installations (portable media)
-
-You can install OpenTTD on external media so you can take it with you, i.e.
-using a USB key, or a USB HDD, etc.
-Create a directory where you shall store the game in (i.e. OpenTTD/).
-Copy the binary (OpenTTD.exe, OpenTTD.app, openttd, etc), baseset/ and your
-openttd.cfg to this directory.
-You can copy binaries for any operating system into this directory, which will
-allow you to play the game on nearly any computer you can attach the external
-media to.
-As always - additional grf files are stored in the newgrf/ dir (for details,
-again, see section 4.1).
-
-### 4.4) Files in tar (archives)
-
-OpenTTD can read files that are in an uncompressed tar (archive), which
-makes it easy to bundle files belonging to the same script, NewGRF or base
-set. Music sets are the only exception as they cannot be stored in a tar
-file due to being played by external applications.
-
-OpenTTD sees each tar archive as the 'root' of its search path. This means that
-having a file with the same path in two different tar files means that one
-cannot be opened, after all only one file will be found first. As such it is
-advisable to put an uniquely named folder in the root of the tar and put all the
-content in that folder. For example, all downloaded content has a path that
-concatenates the name of the content and the version, which makes the path
-unique. For custom tar files it is advised to do this as well.
-
-The normal files are also referred to by their relative path from the search
-directory, this means that also normal files could hide files in a tar as
-long as the relative path from the search path of the normal file is the
-same as the path in the tar file. Again it is advised to have an unique path
-to the normal file so they do not collide with the files from other tar
-files.
-
-## 5.0) OpenTTD features
-
-OpenTTD has a lot of features going beyond the original Transport Tycoon Deluxe
-emulation. Unfortunately, there is currently no comprehensive list of features,
-but there is a basic features list on the web, and some optional features can be
-controlled through the Advanced Settings dialog. We also implement some
-features known from [TTDPatch](https://www.ttdpatch.net).
-
-Several important non-standard controls:
-
-- Ctrl modifies many commands and makes them more powerful. For example Ctrl
-   clicking on signals with the build signal tool changes their behaviour,
-   holding Ctrl while the track build tool is activated changes it to the track
-   removal tool, and so on. See https://wiki.openttd.org/Hidden_features
-   for a non-comprehensive list or look at the tooltips.
-- Ingame console. More information at https://wiki.openttd.org/Console
-- Hovering over a GUI element shows tooltips. This can be changed to right click
-   via the advanced settings.
-
-### 5.1) Logging of potentially dangerous actions
-
-OpenTTD is a complex program, and together with NewGRF, it may show a buggy
-behaviour. But not only bugs in code can cause problems. There are several
-ways to affect game state possibly resulting in program crash or multiplayer
-desyncs.
-
-Easier way would be to forbid all these unsafe actions, but that would affect
-game usability for many players. We certainly do not want that.
-However, we receive bug reports because of this. To reduce time spent with
-solving these problems, these potentially unsafe actions are logged in
-the savegame (including crash.sav). Log is stored in crash logs, too.
-
-Information logged:
-
-- Adding / removing / changing order of NewGRFs
-- Changing NewGRF parameters, loading compatible NewGRF
-- Changing game mode (scenario editor <-> normal game)
-- Loading game saved in a different OpenTTD / TTDPatch / Transport Tycoon Deluxe /
-   original Transport Tycoon version
-- Running a modified OpenTTD build
-- Changing settings affecting NewGRF behaviour (non-network-safe settings)
-- Triggering NewGRF bugs
-
-No personal information is stored.
-
-You can show the game log by typing 'gamelog' in the console or by running
-OpenTTD in debug mode.
-
-### 5.2) Frame rate and performance metrics
-
-The Help menu in-game has a function to open the Frame rate window. This
-window shows various real-time performance statistics, measuring what parts
-of the game require the most processing power currently.
-
-A summary of the statistics can also be retrieved from the console with the
-`fps` command. This is especially useful on dedicated servers, where the
-administrator might want to determine what's limiting performance in a slow
-game.
-
-The frame rate is given as two figures, the simulation rate and the graphics
-frame rate. Usually these are identical, as the screen is rendered exactly
-once per simulated tick, but in the future there might be support for graphics
-and simulation running at different rates. When the game is paused, the
-simulation rate drops to zero.
-
-In addition to the simulation rate, a game speed factor is also calculated.
-This is based on the target simulation speed, which is 30 milliseconds per
-game tick. At that speed, the expected frame rate is 33.33 frames/second, and
-the game speed factor is how close to that target the actual rate is. When
-the game is in fast forward mode, the game speed factor shows how much
-speed up is achieved.
-
-The lower part of the window shows timing statistics for individual parts of
-the game. The times shown are short-term and long-term averages of how long
-it takes to process one tick of game time, all figures are in milliseconds.
-
-Clicking a line in the lower part of the window opens a graph window, giving
-detailed readings on each tick simulated by the game.
-
-The following is an explanation of the different statistics:
-
-- *Game loop* - Total processing time used per simulated "tick" in the game.
-  This includes all pathfinding, world updates, and economy handling.
-- *Cargo handling* - Time spent loading/unloading cargo at stations, and
-  industries and towns sending/retrieving cargo from stations.
-- *Train ticks*, *Road vehicle ticks*, *Ship ticks*, *Aircraft ticks* -
-  Time spent on pathfinding and other processing for each player vehicle type.
-- *World ticks* - Time spent on other world/landscape processing. This
-  includes towns growing, building animations, updates of farmland and trees,
-  and station rating updates.
-- *GS/AI total*, *Game script*, and *AI players* - Time spent running logic
-  for game scripts and AI players. The total may show as less than the current
-  sum of the individual scripts, this is because AI players at lower
-  difficulty settings do not run every game tick, and hence contribute less
-  to the average across all ticks. Keep in mind that the "Current" figure is
-  also an average, just only over short term.
-- *Link graph delay* - Time overruns of the cargo distribution link graph
-  update thread. Usually the link graph is updated in a background thread,
-  but these updates need to synchronise with the main game loop occasionally,
-  if the time spent on link graph updates is longer than the time taken to
-  otherwise simulate the game while it was updating, these delays are counted
-  in this figure.
-- *Graphics rendering* - Total time spent rendering all graphics, including
-  both GUI and world viewports. This typically spikes when panning the view
-  around, and when more things are happening on screen at once.
-- *World viewport rendering* - Isolated time spent rendering just world
-  viewports. If this figure is significantly lower than the total graphics
-  rendering time, most time is spent rendering GUI than rendering world.
-- *Video output* - Speed of copying the rendered graphics to the display
-  adapter. Usually this should be very fast (in the range of 0-3 ms), large
-  values for this can indicate a graphics driver problem.
-- *Sound mixing* - Speed of mixing active audio samples together. Usually
-  this should be very fast (in the range of 0-3 ms), if it is slow, consider
-  switching to the NoSound set.
-
-If the frame rate window is shaded, the title bar will instead show just the
-current simulation rate and the game speed factor.
-
-## 6.0) Configuration file
-
-The configuration file for OpenTTD (openttd.cfg) is in a simple Windows-like
-.INI format. It is mostly undocumented. Almost all settings can be changed
-ingame by using the 'Advanced Settings' window.
-When you cannot find openttd.cfg you should look in the directories as
-described in section 4.2. If you do not have an openttd.cfg OpenTTD will
-create one after closing.
-
-## 7.0) Compiling
-
-### Windows:
-
-You need Microsoft Visual Studio 2015 Update 3 or more recent. Open the project file
-and it should build automatically. In case you want to build with SDL support
-you need to add WITH_SDL to the project settings.
-
-PNG (WITH_PNG), ZLIB (WITH_ZLIB), LZO (WITH_LZO), Freetype (WITH_FREETYPE) and
-LZMA (WITH_LZMA) support is enabled by default. For these to work you need their
-development files. To get them just use vcpkg from https://github.com/Microsoft/vcpkg
-using x86-windows-static and x64-windows-static triplets.
-For more help with VS see docs/Readme_Windows_MSVC.md.
-
-You can also build it using the Makefile with MSYS/MinGW or Cygwin/MinGW.
-Please read the Makefile for more information.
-
-### Solaris, FreeBSD, OpenBSD:
-
-Use '`gmake`', but do a '`./configure`' before the first build.
-
-### Linux/Unix:
-
-OpenTTD can be built with GNU '`make`'. On non-GNU systems it is called '`gmake`'.
-However, for the first build one has to do a '`./configure`' first.
-
-### macOS:
-
-Use '`make`' or Xcode (which will then call make for you)
-This will give you a binary for your CPU type (PPC/Intel)
-However, for the first build one has to do a '`./configure`' first.
-To make a universal binary type '`./configure --enabled-universal`'
-instead of '`./configure`'.
-
-### BeOS:
-
-Use '`make`', but do a '`./configure`' before the first build.
-
-### MorphOS:
-
-Use '`make`'. However, for the first build one has to do a '`./configure`'
-first. Note that you need the MorphOS SDK, latest libnix updates (else C++
-parts of OpenTTD will not build) and the powersdl.library SDK. Optionally libz,
-libpng and freetype2 developer files.
-
-### OS/2:
-
-A comprehensive GNU build environment is required to build the OS/2 version.
-See the docs/Readme_OS2.txt file for more information.
-
-### DOS:
-
-A build environment with DJGPP is needed as well as libraries such as
-Allegro, zlib and libpng, which all can be downloaded from the DJGPP
-website. Compilation is straight forward: use '`make`', but do a '`./configure`'
-before the first build. The build binary will need cwsdpmi.exe to be in
-the same directory as the openttd executable. cwsdpmi.exe can be found in
-the os/dos/cwsdpmi subdirectory. If you compile with stripping turned on a
-binary will be generated that does not need cwsdpmi.exe by adding the
-cswdstub.exe to the created OpenTTD binary.
-
-### 7.1) Required/optional libraries
-
-The following libraries are used by OpenTTD for:
-
-- libSDL/liballegro: hardware access (video, sound, mouse)
-- zlib: (de)compressing of old (0.3.0-1.0.5) savegames, content downloads,
-   heightmaps
-- liblzo2: (de)compressing of old (pre 0.3.0) savegames
-- liblzma: (de)compressing of savegames (1.1.0 and later)
-- libpng: making screenshots and loading heightmaps
-- 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.
-Without libSDL/liballegro on non-Windows and non-macOS machines you have
-no graphical user interface; you would be building a dedicated server.
+## 1.5) Add-on content / mods
 
-### 7.2) Supported compilers
+OpenTTD features multiple types of add-on content, which modify gameplay in different ways.
 
-The following compilers are known to compile OpenTTD:
+Most types of add-on content can be downloaded within OpenTTD via the 'Check Online Content' button in the main menu.
 
-- Microsoft Visual C++ (MSVC) 2015, 2017 and 2019.
-- GNU Compiler Collection (GCC) 3.3 - 4.4, 4.6 - 4.8.
-    - Versions 4.1 and earlier give bogus warnings about uninitialised variables.
-    - Versions 4.4, 4.6 give bogus warnings about freeing non-heap objects.
-    - Versions 4.6 and later give invalid warnings when lto is enabled.
-- Intel C++ Compiler (ICC) 12.0.
-- Clang/LLVM 2.9 - 3.0
-   Version 2.9 gives bogus warnings about code nonconformity.
+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).
 
-The following compilers are known not to compile OpenTTD:
+### 1.5.1) AI opponents
 
-- Microsoft Visual C++ (MSVC) 2013 and earlier.
-   These old versions do not support modern C++ language features.
-- GNU Compiler Collection (GCC) 3.2 and earlier.
-   These old versions fail due to OpenTTD's template usage.
-- GNU Compiler Collection (GCC) 4.5. It optimizes enums too aggressively.
-   See https://github.com/OpenTTD/OpenTTD/issues/5513 and references therein.
-- Intel C++ Compiler (ICC) 11.1 and earlier.
-    - Version 10.0 and earlier fail a configure check and fail with recent
-       system headers.
-    - Version 10.1 fails to compile station_gui.cpp.
-    - Version 11.1 fails with an internal error when compiling network.cpp.
-- Clang/LLVM 2.8 and earlier.
-- (Open) Watcom.
+OpenTTD comes without AI opponents, so if you want to play with AIs you have to download them.
 
-If any of these compilers can compile OpenTTD again, please let us know.
-Patches to support more compilers are welcome.
+The easiest way is via the 'Check Online Content' button in the main menu.
 
-### 7.3) Compilation of base sets
+You can select some AIs that you think are compatible with your playing style.
 
-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/download-grfcodec.
-The compilation of these extra graphics does generally not happen, unless
-you remove the graphics file using '`make maintainer-clean`'.
+AI help and discussions may also be found in the [AI section of the forum](https://www.tt-forums.net/viewforum.php?f=65).
 
-Re-compilation of the base sets, thus also use of '`--maintainer-clean`' can
-leave the repository in a modified state as different grfcodec versions can
-cause binary differences in the resulting grf. Also translations might have
-been added for the base sets which are not yet included in the base set
-information files. Use the configure option '`--without-grfcodec`' to avoid
-modification of the base set files by the build process.
+### 1.5.2) Scenarios and height maps
 
-## 8.0) Translating
+Scenarios and heightmaps can be added via the 'Check Online Content' button in the main menu.
 
-See https://www.openttd.org/development for up-to-date information.
+### 1.5.3) NewGRFs
 
-The use of the online Translator service, located at
-https://translator.openttd.org, is highly encouraged. For getting an account
-simply follow the guidelines in the FAQ of the translator website.
+A wide range of add-content is available as NewGRFs, including vehicles, industries, stations, landscape objects, town names and more.
 
-If for some reason the website is down for a longer period of time, the
-information below might be of help.
+NewGRFs can be added via the 'Check Online Content' button in the main menu.
 
-Please contact the translations manager (https://www.openttd.org/contact)
-before beginning the translation process! This avoids double work, as
-someone else may have already started translating to the same language.
+See also the wiki [guide to NewGRFs](https://wiki.openttd.org/en/Manual/NewGRF) and [the forum graphics development section](https://www.tt-forums.net/viewforum.php?f=66).
 
-### 8.1) Translation
+### 1.5.4) Game scripts
 
-So, now that you have notified the development team about your intention to
-translate (You did, right? Of course you did.) you can pick up english.txt
-(found in the Git repository under /src/lang) and translate.
+Game scripts can provide additional challenges or changes to the standard OpenTTD gameplay, for example setting transport goals, or changing town growth behaviour.
 
-You must change the first two lines of the file appropriately:
+Game scripts can be added via the 'Check Online Content' button in the main menu.
 
-    ##name English-Name-Of-Language
-    ##ownname Native-Name-Of-Language
-
-Note: Do not alter the following parts of the file:
+See also the wiki [guide to game scripts](https://wiki.openttd.org/en/Manual/Game%20script) and [the forum graphics game script section](https://www.tt-forums.net/viewforum.php?f=65).
 
-- String identifiers (the first word on each line)
-- Parts of the strings which are in curly braces (such as {STRING})
-- Lines beginning with ## (such as ##id), other than the first two lines
-   of the file
-
-### 8.2) Previewing
-
-In order to view the translation in the game, you need to compile your language
-file with the strgen utility. As this utility is tailored to a specific OpenTTD
-version, you need to compile it yourself. Just take the normal OpenTTD sources
-and build that. During the build process the strgen utility will be made.
+### 1.6) OpenTTD directories
 
-strgen is a command-line utility. It takes the language filename as parameter.
+OpenTTD uses its own directory structure to store game data, add-on content etc.
 
-Example:
+For more information, see the [directory structure guide](./docs/directory_structure.md).
 
-    strgen lang/german.txt
+### 1.7) Compiling OpenTTD
 
-This results in compiling german.txt and produces another file named german.lng.
-Any missing strings are replaced with the English strings. Note that it looks
-for english.txt in the lang subdirectory, which is where your language file
-should also be.
-
-That is all! You should now be able to select the language in the game options.
+If you want to compile OpenTTD from source, instructions can be found in [COMPILING.md](./COMPILING.md).
 
-## 9.0) Troubleshooting
 
-To see all startup options available to you, start OpenTTD with the
-'`./openttd -h`' option. This might help you tweak some of the settings.
-
-If the game is acting strange and you feel adventurous you can try the
-'`-d [[<name>=]<level>]`' flag, where the higher levels will give you more
-debugging output. The 'name' variable can help you to display only some type of
-debugging messages. This is mostly undocumented so best is to look in the
-source code file debug.c for the various debugging types. For more information
-look at https://wiki.openttd.org/Command_line.
-
-The most frequent problem is missing data files. Please install OpenGFX and
-possibly OpenSFX and OpenMSX. See section 4.1.1 for more information.
-
-Under certain circumstance, especially on Ubuntu OpenTTD can be extremely slow
-and/or freeze. See known-bugs.txt for more information and how to solve this
-problem on your computer.
-
-Under Windows 98 and lower it is impossible to use a dedicated server; it will
-fail to start. Perhaps this is for the better because those OSes are not known
-for their stability.
-
-With the added support for font-based text selecting a non-latin language can
-result in lots of question marks ('?') being shown on screen. Please open your
-configuration file (openttd.cfg - see Section 4.2 for where to find it)
-and add a suitable font for the small, medium and / or large font, e.g.:
+## 2.0) Contact and Community
 
-    small_font = "Tahoma"
-    medium_font = "Tahoma"
-    large_font = "Tahoma"
-
-You should use a font name like 'Tahoma' or a path to the desired font.
-
-Any NewGRF file used in a game is stored inside the savegame and will refuse to
-load if you do not have that NewGRF file available. A list of missing files can
-be viewed in the NewGRF window accessible from the file load dialogue window.
-
-You can try to obtain the missing files from that NewGRF dialogue or – if they
-are not available online – you can search manually through our
-[forum's graphics development section](https://www.tt-forums.net/viewforum.php?f=66)
-or [GRFCrawler](https://grfcrawler.tt-forums.net). Put the NewGRF files in
-OpenTTD's newgrf folder (see section 4.2 'OpenTTD directories') and rescan the
-list of available NewGRFs. Once you have all missing files, you are set to go.

+Finds the LZO library.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This will define the following variables:
+
+``LZO_FOUND``
+  True if the system has the LZO library.
+``LZO_INCLUDE_DIRS``
+  Include directories needed to use LZO.
+``LZO_LIBRARIES``
+  Libraries needed to link to LZO.
+``LZO_VERSION``
+  The version of the LZO library which was found.
+
+Cache Variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set:
+
+``LZO_INCLUDE_DIR``
+  The directory containing ``lzo/lzo1x.h``.
+``LZO_LIBRARY``
+  The path to the LZO library.
