+The simplest way of installing GF is with the command:
 ```
 cabal install
 ```
-or:
-```
-stack install
-```
-Note that if you are unlucky to have Cabal 3.0 or later, then it uses
-the so-called Nix style commands. Using those for GF development is
-a pain. Every time when you change something in the source code, Cabal
-will generate a new folder for GF to look for the GF libraries and
-the GF cloud. Either reinstall everything with every change in the
-compiler, or be sane and stop using cabal-install. Instead you can do:
-```
-runghc Setup.hs configure
-runghc Setup.hs build
-sudo runghc Setup.hs install
-```
-The script will install the GF dependencies globally. The only solution
-to the Nix madness that I found is radical:
 
-  "No person, no problem" (Нет человека – нет проблемы).
+This can be broken down into the usual sub-steps:
+```
+cabal configure
+cabal build
+cabal copy
+```

 ## About this repository
 

RELEASE.md

@@ -1,69 +0,0 @@
-# GF Core releases
-
-**Note:**
-The RGL is now released completely separately from GF Core.
-See the [RGL's RELEASE.md](https://github.com/GrammaticalFramework/gf-rgl/blob/master/RELEASE.md).
-
-## Creating a new release
-
-### 1. Prepare the repository
-
-**Web pages**
-
-1. Create `download/index-X.Y.md` with installation instructions.
-2. Create `download/release-X.Y.md` with changelog information.
-3. Update `download/index.html` to redirect to the new version.
-4. Add announcement in news section in `index.html`.
-
-**Version numbers**
-
-1. Update version number in `gf.cabal` (ommitting `-git` suffix).
-2. Add a new line in `debian/changelog`.
-
-### 2. Create GitHub release
-
-1. When the above changes are committed to the `master` branch in the repository
-  and pushed, check that all CI workflows are successful (fixing as necessary):
-  - <https://github.com/GrammaticalFramework/gf-core/actions>
-  - <https://travis-ci.org/github/GrammaticalFramework/gf-core>
-2. Create a GitHub release [here](https://github.com/GrammaticalFramework/gf-core/releases/new):
-  - Tag version format `RELEASE-X.Y`
-  - Title: "GF X.Y"
-  - Description: mention major changes since last release
-3. Publish the release to trigger the building of the binary packages (below).
-
-### 3. Binary packages
-
-The binaries will be built automatically by GitHub Actions when the release is created,
-but the generated _artifacts_ must be manually attached to the release as _assets_.
-
-1. Go to the [actions page](https://github.com/GrammaticalFramework/gf-core/actions) and click "Build Binary Packages" under _Workflows_.
-2. Choose the workflow run corresponding to the newly created release.
-3. Download the artifacts locally. Extract the Ubuntu and macOS ones to get the `.deb` and `.pkg` files.
-4. Go back to the [releases page](https://github.com/GrammaticalFramework/gf-core/releases) and click to edit the release information.
-5. Add the downloaded artifacts as release assets, giving them names with format `gf-X.Y-PLATFORM.EXT` (e.g. `gf-3.11-macos.pkg`).
-
-### 4. Upload to Hackage
-
-In order to do this you will need to be added the [GF maintainers](https://hackage.haskell.org/package/gf/maintainers/) on Hackage.
-
-1. Run `stack sdist --test-tarball` and address any issues.
-2. Upload the package, either:
-    1. **Manually**: visit <https://hackage.haskell.org/upload> and upload the file generated by the previous command.
-    2. **via Stack**: `stack upload . --candidate`
-3. After testing the candidate, publish it:
-    1. **Manually**: visit <https://hackage.haskell.org/package/gf-X.Y.Z/candidate/publish>
-    1. **via Stack**: `stack upload .`
-4. If the documentation-building fails on the Hackage server, do:
-```
-cabal v2-haddock --builddir=dist/docs --haddock-for-hackage --enable-doc
-cabal upload --documentation dist/docs/*-docs.tar.gz
-```
-
-## Miscellaneous
-
-### What is the tag `GF-3.10`?
-
-For GF 3.10, the Core and RGL repositories had already been separated, however
-the binary packages still included the RGL. `GF-3.10` is a tag that was created
-in both repositories ([gf-core](https://github.com/GrammaticalFramework/gf-core/releases/tag/GF-3.10) and [gf-rgl](https://github.com/GrammaticalFramework/gf-rgl/releases/tag/GF-3.10)) to indicate which versions of each went into the binaries.

-## unsupported token gluing `foo + bar`
-
-There was a problem in an expression using +, e.g. `foo + bar`.
-This can be due to two causes, check which one applies in your case.
-
-1. You are trying to use + on runtime arguments. Even if you are using
-`foo + bar` in an oper, make sure that the oper isn't called in a
-linearization that takes arguments. Both of the following are illegal:
-
-    lin Test foo bar = foo.s + bar.s          -- explicit + in a lin
-    lin Test foo bar = opWithPlus foo bar     -- the oper uses +
-
-2. One of the arguments in `foo + bar` is a bound variable
-from pattern matching a string, but the cases are non-exhaustive.
-Example:
-    case "test" of {
-      x + "a" => x + "b"   -- no applicable case for "test", so x = ???
-    } ;
-
-You can fix this by adding a catch-all case in the end:
-    { x + "a" => x + "b" ;
-      _       => "default case" } ;
-
-3. If neither applies to your problem, submit a bug report and we
-will update the error message and this documentation.

-GF Developer's Guide: Old installation instructions with Cabal
-
-
-This page contains the old installation instructions from the [Developer's Guide ../doc/gf-developers.html].
-We recommend Stack as a primary installation method, because it's easier for a Haskell beginner, and we want to keep the main instructions short.
-But if you are an experienced Haskeller and want to keep using Cabal, here are the old instructions using ``cabal install``.
-
-Note that some of these instructions may be outdated. Other parts may still be useful.
-
-== Compilation from source with Cabal ==
-
-The build system of GF is based on //Cabal//, which is part of the
-Haskell Platform, so no extra steps are needed to install it. In the simplest
-case, all you need to do to compile and install GF, after downloading the
-source code as described above, is
-
-```
-$ cabal install
-```
-
-This will automatically download any additional Haskell libraries needed to
-build GF. If this is the first time you use Cabal, you might need to run
-``cabal update`` first, to update the list of available libraries.
-
-If you want more control, the process can also be split up into the usual
-//configure//, //build// and //install// steps.
-
-=== Configure ===
-
-During the configuration phase Cabal will check that you have all
-necessary tools and libraries needed for GF. The configuration is
-started by the command:
-
-```
-$ cabal configure
-```
-
-If you don't see any error message from the above command then you
-have everything that is needed for GF. You can also add the option
-``-v`` to see more details about the configuration.
-
-You can use ``cabal configure --help`` to get a list of configuration options.
-
-=== Build ===
-
-The build phase does two things. First it builds the GF compiler from
-the Haskell source code and after that it builds the GF Resource Grammar
-Library using the already build compiler.  The simplest command is:
-
-```
-$ cabal build
-```
-
-Again you can add the option ``-v`` if you want to see more details.
-
-==== Parallel builds ====
-
-If you have Cabal>=1.20 you can enable parallel compilation by using
-
-```
-$ cabal build -j
-```
-
-or by putting a line
-```
-jobs: $ncpus
-```
-in your ``.cabal/config`` file. Cabal
-will pass this option to GHC when building the GF compiler, if you
-have GHC>=7.8.
-
-Cabal also passes ``-j`` to GF to enable parallel compilation of the
-Resource Grammar Library. This is done unconditionally to avoid
-causing problems for developers with Cabal<1.20. You can disable this
-by editing the last few lines in ``WebSetup.hs``.
-
-=== Install ===
-
-After you have compiled GF you need to install the executable and libraries
-to make the system usable.
-
-```
-$ cabal copy
-$ cabal register
-```
-
-This command installs the GF compiler for a single user, in the standard
-place used by Cabal.
-On Linux and Mac this could be ``$HOME/.cabal/bin``.
-On Mac it could also be ``$HOME/Library/Haskell/bin``.
-On Windows this is ``C:\Program Files\Haskell\bin``.
-
-The compiled GF Resource Grammar Library will be installed
-under the same prefix, e.g. in
-``$HOME/.cabal/share/gf-3.3.3/lib`` on Linux and
-in ``C:\Program Files\Haskell\gf-3.3.3\lib`` on Windows.
-
-If you want to install in some other place then use the ``--prefix``
-option during the configuration phase.
-
-=== Clean ===
-
-Sometimes you want to clean up the compilation and start again from clean
-sources. Use the clean command for this purpose:
-
-```
-$ cabal clean
-```
-
-
-%=== SDist ===
-%
-%You can use the command:
-%
-%% This does *NOT* include everything that is needed // TH 2012-08-06
-%```
-%$ cabal sdist
-%```
-%
-%to prepare archive with all source codes needed to compile GF.
-
-=== Known problems with Cabal ===
-
-Some versions of Cabal (at least version 1.16) seem to have a bug that can
-cause the following error:
-
-```
-Configuring gf-3.x...
-setup: Distribution/Simple/PackageIndex.hs:124:8-13: Assertion failed
-```
-
-The exact cause of this problem is unclear, but it seems to happen
-during the configure phase if the same version of GF is already installed,
-so a workaround is to remove the existing installation with
-
-```
-ghc-pkg unregister gf
-```
-
-You can check with ``ghc-pkg list gf`` that it is gone.
-
-== Compilation with make ==
-
-If you feel more comfortable with Makefiles then there is a thin Makefile
-wrapper arround Cabal for you. If you just type:
-```
-$ make
-```
-the configuration phase will be run automatically if needed and after that
-the sources will be compiled.
-
-%% cabal build rgl-none does not work with recent versions of Cabal
-%If you don't want to compile the resource library
-%every time then you can use:
-%```
-%$ make gf
-%```
-
-For installation use:
-```
-$ make install
-```
-For cleaning:
-```
-$ make clean
-```
-%and to build source distribution archive run:
-%```
-%$ make sdist
-%```
-
-
-== Partial builds of RGL ==
-
-**NOTE**: The following doesn't work with recent versions of ``cabal``. //(This comment was left in 2015, so make your own conclusions.)//
-%% // TH 2015-06-22
-
-%Sometimes you just want to work on the GF compiler and don't want to
-%recompile the resource library after each change. In this case use
-%this extended command:
-
-%```
-%$ cabal build rgl-none
-%```
-
-The resource grammar library can be compiled in two modes: with present
-tense only and with all tenses. By default it is compiled with all
-tenses. If you want to use the library with only present tense you can
-compile it in this special mode with the command:
-
-```
-$ cabal build present
-```
-
-You could also control which languages you want to be recompiled by
-adding the option ``langs=list``. For example the following command
-will compile only the English and the Swedish language:
-
-```
-$ cabal build langs=Eng,Swe
-```

 To build GF from source you need to install some tools on your
-system: the Haskell build tool //Stack//, the version control software //Git// and the //Haskeline// library.

+**On Linux** the best option is to install the tools via the standard

+in Ubuntu or the corresponding tool in other popular Linux distributions.
+Or, from a Terminal window, the following command should be enough:
 
-%**On Mac OS and Windows**, the tools can be downloaded from their respective
-%web sites, as described below.
-
-=== Stack ===
-The primary installation method is via //Stack//.
-(You can also use Cabal, but we recommend Stack to those who are new to Haskell.)
-
-To install Stack:
-
-- **On Linux and Mac OS**, do either
-
-    ``$ curl -sSL https://get.haskellstack.org/ | sh``
-
-  or
-
-    ``$ wget -qO- https://get.haskellstack.org/ | sh``
+- On Ubuntu: ``sudo apt-get install haskell-platform git libghc6-haskeline-dev``
+- On Fedora: ``sudo dnf install haskell-platform git ghc-haskeline-devel``
 
 
-- **On other operating systems**, see the [installation guide https://docs.haskellstack.org/en/stable/install_and_upgrade].
+**On Mac OS and Windows**, the tools can be downloaded from their respective
+web sites, as described below.
 
+=== The Haskell Platform ===
 
-%If you already have Stack installed, upgrade it to the latest version by running: ``stack upgrade``
+GF is written in Haskell, so first of all you need
+the //Haskell Platform//, e.g. version 8.0.2 or 7.10.3. Downloads
+and installation instructions are available from here:
+
+    http://hackage.haskell.org/platform/
+
+Once you have installed the Haskell Platform, open a terminal
+(Command Prompt on Windows) and try to execute the following command:
+```
+$ ghc --version
+```
+This command should show you which version of GHC you have. If the installation
+of the Haskell Platform	 was successful you should see a message like:
+
+```
+The Glorious Glasgow Haskell Compilation System, version 8.0.2
+```
+
+Other required tools included in the Haskell Platform are
+[Cabal http://www.haskell.org/cabal/],
+[Alex http://www.haskell.org/alex/]
+and
+[Happy http://www.haskell.org/happy/].
+
+%=== Darcs ===
+%
+%To get the GF source code, you also need //Darcs//, version 2 or later.
+%Darcs 2.10 is recommended (July 2015).
+%
+%//Darcs//
+%is a distributed version control system, see http://darcs.net/ for
+%more information. There are precompiled packages for many platforms
+%available and source code if you want to compile it yourself. Darcs
+%is also written in Haskell and so you can use GHC to compile it.
 
 
 === Git ===

-  - On Ubuntu: ``sudo apt-get install git-all``
-  - On Fedora: ``sudo dnf install git-all``
-
-
-- **On other operating systems**, see
-https://git-scm.com/book/en/v2/Getting-Started-Installing-Git for installation.
-
-
-
-=== Haskeline ===
+=== The haskeline library ===
 
 GF uses //haskeline// to enable command line editing in the GF shell.
+This should work automatically on Mac OS and Windows, but on Linux one
+extra step is needed to make sure the C libraries (terminfo)
+required by //haskeline// are installed.  Here is one way to do this:

+== Getting the source ==
 
-Once you have all tools in place you can get the GF source code from
-[GitHub https://github.com/GrammaticalFramework/]:
+Once you have all tools in place you can get the GF source code. If you
+just want to compile and use GF then it is enough to have read-only
+access. It is also possible to make changes in the source code but if you
+want these changes to be applied back to the main source repository you will
+have to send the changes to us.  If you plan to work continuously on
+GF then you should consider getting read-write access.
 
-- https://github.com/GrammaticalFramework/gf-core for the GF compiler
-- https://github.com/GrammaticalFramework/gf-rgl for the Resource Grammar Library
+=== Read-only access ===
 
+==== Getting a fresh copy for read-only access ====
 
-=== Read-only access: clone the main repository ===
-
-If you only want to compile and use GF, you can just clone the repositories as follows:
+Anyone can get the latest development version of GF by running:
 
 ```
-  $ git clone https://github.com/GrammaticalFramework/gf-core.git
-  $ git clone https://github.com/GrammaticalFramework/gf-rgl.git
+$ git clone https://github.com/GrammaticalFramework/gf-core.git
+$ git clone https://github.com/GrammaticalFramework/gf-rgl.git
 ```
 
-To get new updates, run the following anywhere in your local copy of the repository:
+This will create directories ``gf-core`` and ``gf-rgl`` in the current directory.
+
+
+==== Updating your copy ====
+
+To get all new patches from each repo:
+```
+$ git pull
+```
+This can be done anywhere in your local repository.
+
+
+==== Recording local changes ====[record]
+
+Since every copy is a repository, you can have local version control
+of your changes.
+
+If you have added files, you first need to tell your local repository to
+keep them under revision control:
 
 ```
-  $ git pull
+$ git add file1 file2 ...
 ```
 
-=== Contribute your changes: fork the main repository ===
-
-If you want the possibility to contribute your changes,
-you should create your own fork, do your changes there,
-and then send a pull request to the main repository.
-
-+ **Creating and cloning a fork  —**
-See GitHub documentation for instructions how to [create your own fork https://docs.github.com/en/get-started/quickstart/fork-a-repo]
-of the repository. Once you've done it, clone the fork to your local computer.
+To record changes, use:
 
 ```
-  $ git clone https://github.com/<YOUR_USERNAME>/gf-core.git
+$ git commit file1 file2 ...
 ```
 
-+ **Updating your copy —**
-Once you have cloned your fork, you need to set up the main repository as a remote:
+This creates a patch against the previous version and stores it in your
+local repository. You can record any number of changes before
+pushing them to the main repo. In fact, you don't have to push them at
+all if you want to keep the changes only in your local repo.
+
+Instead of enumerating all modified files on the command line,
+you can use the flag ``-a`` to automatically record //all// modified
+files. You still need to use ``git add`` to add new files.
+
+
+=== Read-write access ===
+
+If you are a member of the GF project on GitHub, you can push your
+changes directly to the GF git repository on GitHub.
 
 ```
-  $ git remote add upstream https://github.com/GrammaticalFramework/gf-core.git
+$ git push
 ```
 
-Then you can get the latest updates by running the following:
+It is also possible for anyone else to contribute by
 
-```
-  $ git pull upstream master
-```
-
-+ **Recording local changes —**
-See Git tutorial on how to [record and push your changes https://git-scm.com/book/en/v2/Git-Basics-Recording-Changes-to-the-Repository] to your fork.
-
-+ **Pull request —**
-When you want to contribute your changes to the main gf-core repository,
-[create a pull request https://docs.github.com/en/github/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request]
-from your fork.
+- creating a fork of the GF repository on GitHub,
+- working with local clone of the fork (obtained with ``git clone``),
+- pushing changes to the fork,
+- and finally sending a pull request.
 
 
 
-If you want to contribute to the RGL as well, do the same process for the RGL repository.
+== Compilation from source with Cabal ==
 
-
-== Compilation from source ==
-
-By now you should have installed Stack and Haskeline, and cloned the Git repository on your own computer, in a directory called ``gf-core``.
-
-=== Primary recommendation: use Stack ===
-
-Open a terminal, go to the top directory (``gf-core``), and type the following command.
-
-```
-$ stack install
-```
-
-It will install GF and all necessary tools and libraries to do that.
-
-
-=== Alternative: use Cabal ===
-You can also install GF using Cabal, if you prefer Cabal to Stack. In that case, you may need to install some prerequisites yourself.
-
-The actual installation process is similar to Stack: open a terminal, go to the top directory (``gf-core``), and type the following command.
+The build system of GF is based on //Cabal//, which is part of the
+Haskell Platform, so no extra steps are needed to install it. In the simplest
+case, all you need to do to compile and install GF, after downloading the
+source code as described above, is
 
 ```
 $ cabal install
 ```
 
-//The old (potentially outdated) instructions for Cabal are moved to a [separate page ../doc/gf-developers-old-cabal.html]. If you run into trouble with ``cabal install``, you may want to take a look.//
+This will automatically download any additional Haskell libraries needed to
+build GF. If this is the first time you use Cabal, you might need to run
+``cabal update`` first, to update the list of available libraries.
 
-== Compiling GF with C runtime system support ==
+If you want more control, the process can also be split up into the usual
+//configure//, //build// and //install// steps.
 
-The C runtime system is a separate implementation of the PGF runtime services.
+=== Configure ===
+
+During the configuration phase Cabal will check that you have all
+necessary tools and libraries needed for GF. The configuration is
+started by the command:
+
+```
+$ cabal configure
+```
+
+If you don't see any error message from the above command then you
+have everything that is needed for GF. You can also add the option
+``-v`` to see more details about the configuration.
+
+You can use ``cabal configure --help`` to get a list of configuration options.
+
+=== Build ===
+
+The build phase does two things. First it builds the GF compiler from
+the Haskell source code and after that it builds the GF Resource Grammar
+Library using the already build compiler.  The simplest command is:
+
+```
+$ cabal build
+```
+
+Again you can add the option ``-v`` if you want to see more details.
+
+==== Parallel builds ====
+
+If you have Cabal>=1.20 you can enable parallel compilation by using
+
+```
+$ cabal build -j
+```
+
+or by putting a line
+```
+jobs: $ncpus
+```
+in your ``.cabal/config`` file. Cabal
+will pass this option to GHC when building the GF compiler, if you
+have GHC>=7.8.
+
+Cabal also passes ``-j`` to GF to enable parallel compilation of the
+Resource Grammar Library. This is done unconditionally to avoid
+causing problems for developers with Cabal<1.20. You can disable this
+by editing the last few lines in ``WebSetup.hs``.
+
+
+==== Partial builds ====
+
+**NOTE**: The following doesn't work with recent versions of ``cabal``.
+%% // TH 2015-06-22
+
+Sometimes you just want to work on the GF compiler and don't want to
+recompile the resource library after each change. In this case use
+this extended command:
+
+```
+$ cabal build rgl-none
+```
+
+The resource library could also be compiled in two modes: with present
+tense only and with all tenses. By default it is compiled with all
+tenses. If you want to use the library with only present tense you can
+compile it in this special mode with the command:
+
+```
+$ cabal build present

+
+You could also control which languages you want to be recompiled by
+adding the option ``langs=list``. For example the following command
+will compile only the English and the Swedish language:
+
+```
+$ cabal build langs=Eng,Swe
+```
+
+=== Install ===
+
+After you have compiled GF you need to install the executable and libraries
+to make the system usable.
+
+```
+$ cabal copy
+$ cabal register
+```
+
+This command installs the GF compiler for a single user, in the standard
+place used by Cabal.
+On Linux and Mac this could be ``$HOME/.cabal/bin``.
+On Mac it could also be ``$HOME/Library/Haskell/bin``.
+On Windows this is ``C:\Program Files\Haskell\bin``.
+
+The compiled GF Resource Grammar Library will be installed
+under the same prefix, e.g. in
+``$HOME/.cabal/share/gf-3.3.3/lib`` on Linux and
+in ``C:\Program Files\Haskell\gf-3.3.3\lib`` on Windows.
+
+If you want to install in some other place then use the ``--prefix``
+option during the configuration phase.
+
+=== Clean ===
+
+Sometimes you want to clean up the compilation and start again from clean
+sources. Use the clean command for this purpose:
+
+```
+$ cabal clean
+```
+
+
+%=== SDist ===
+%
+%You can use the command:
+%
+%% This does *NOT* include everything that is needed // TH 2012-08-06
+%```
+%$ cabal sdist
+%```
+%
+%to prepare archive with all source codes needed to compile GF.
+
+=== Known problems with Cabal ===
+
+Some versions of Cabal (at least version 1.16) seem to have a bug that can
+cause the following error:
+
+```
+Configuring gf-3.x...
+setup: Distribution/Simple/PackageIndex.hs:124:8-13: Assertion failed
+```
+
+The exact cause of this problem is unclear, but it seems to happen
+during the configure phase if the same version of GF is already installed,
+so a workaround is to remove the existing installation with
+
+```
+ghc-pkg unregister gf
+```
+
+You can check with ``ghc-pkg list gf`` that it is gone.
+
+== Compilation with make ==
+
+If you feel more comfortable with Makefiles then there is a thin Makefile
+wrapper arround Cabal for you. If you just type:
+```
+$ make
+```
+the configuration phase will be run automatically if needed and after that
+the sources will be compiled.
+
+%% cabal build rgl-none does not work with recent versions of Cabal
+%If you don't want to compile the resource library
+%every time then you can use:
+%```
+%$ make gf
+%```
+
+For installation use:
+```
+$ make install
+```
+For cleaning:
+```
+$ make clean
+```
+%and to build source distribution archive run:
+%```
+%$ make sdist
+%```
+
+== Compiling GF with C run-time system support ==
+
+The C run-time system is a separate implementation of the PGF run-time services.
 It makes it possible to work with very large, ambiguous grammars, using
-probabilistic models to obtain probable parses. The C runtime system might
-also be easier to use than the Haskell runtime system on certain platforms,
+probabilistic models to obtain probable parses. The C run-time system might
+also be easier to use than the Haskell run-time system on certain platforms,
 e.g. Android and iOS.
 
-To install the C runtime system, go to the ``src/runtime/c`` directory.
+To install the C run-time system, go to the ``src/runtime/c`` directory
+%and follow the instructions in the ``INSTALL`` file.
+and use the ``install.sh`` script:
+```
+bash setup.sh configure

+bash setup.sh install
+```
+This will install
+the C header files and libraries need to write C programs that use PGF grammars.
+Some example C programs are included in the ``utils`` subdirectory, e.g.
+``pgf-translate.c``.
 
-- **On Linux and Mac OS —**
-  You should have autoconf, automake, libtool and make.
-  If you are missing some of them, follow the
-  instructions in the [INSTALL https://github.com/GrammaticalFramework/gf-core/blob/master/src/runtime/c/INSTALL] file.
-
-  Once you have the required libraries, the easiest way to install the C runtime is to use the ``install.sh`` script. Just type
-
-  ``$ bash install.sh``
-
-  This will install the C header files and libraries need to write C programs
-  that use PGF grammars.
-
-%  If this doesn't work for you, follow the manual instructions in the [INSTALL https://github.com/GrammaticalFramework/gf-core/blob/master/src/runtime/c/INSTALL] file under your operating system.
-
-- **On other operating systems —** Follow the instructions in the
-[INSTALL https://github.com/GrammaticalFramework/gf-core/blob/master/src/runtime/c/INSTALL] file under your operating system.
-
-
-
-Depending on what you want to do with the C runtime, you can follow one or more of the following steps.
-
-=== Use the C runtime from another programming language ===[bindings]
-
-% **If you just want to use the C runtime from Python, Java, or Haskell, you don't need to change your GF installation.**
-
-- **What —**
-This is the most common use case for the C runtime: compile
-your GF grammars into PGF with the standard GF executable,
-and manipulate the PGFs from another programming language,
-using the bindings to the C runtime.
-
-
-- **How —**
-The Python, Java and Haskell bindings are found in the
-``src/runtime/{python,java,haskell-bind}`` directories,
-respecively. Compile them by following the instructions
-in the ``INSTALL`` or ``README`` files in those directories.
-
-The Python library can also be installed from PyPI using ``pip install pgf``.
-
-
-//If you are on Mac and get an error about ``clang`` version, you can try some of [these solutions https://stackoverflow.com/questions/63972113/big-sur-clang-invalid-version-error-due-to-macosx-deployment-target]—but be careful before removing any existing installations.//
-
-
-=== Use GF shell with C runtime support ===
-
-- **What —**
-If you want to use the GF shell with C runtime functionalities, then you need to (re)compile GF with special flags.
-
-The GF shell can be started with ``gf -cshell`` or ``gf -crun`` to use
-the C run-time system instead of the Haskell run-time system.
-Only limited functionality is available when running the shell in these
-modes (use the ``help`` command in the shell for details).
-
-(Re)compiling your GF with these flags will also give you
-Haskell bindings to the C runtime, as a library called ``PGF2``,
-but if you want Python or Java bindings, you need to do [the previous step #bindings].
-
-% ``PGF2``: a module to import in Haskell programs, providing a binding to the C run-time system.
-
-- **How —**
-If you use cabal, run the following command:
+When the C run-time system is installed, you can install GF with C run-time
+support by doing
 
 ```
-cabal install -fc-runtime
+cabal install -fserver -fc-runtime
 ```
+from the top directory. This give you three new things:
 
-from the top directory (``gf-core``).
+- ``PGF2``: a module to import in Haskell programs, providing a binding to
+   the C run-time system.
 
-If you use stack, uncomment the following lines in the ``stack.yaml`` file:
+- The GF shell can be started with ``gf -cshell`` or ``gf -crun`` to use
+  the C run-time system instead of the Haskell run-time system.
+  Only limited functionality is available when running the shell in these
+  modes (use the ``help`` command in the shell for details).
 
-```
-flags:
-   gf:
-     c-runtime: true
-extra-lib-dirs:
-   - /usr/local/lib
-```
-and then run ``stack install`` from the top directory (``gf-core``).
+- ``gf -server`` mode is extended with new requests to call the C run-time
+   system, e.g. ``c-parse``, ``c-linearize`` and ``c-translate``.
 
 
-//If you get an "``error while loading shared libraries``" when trying to run GF with C runtime, remember to declare your ``LD_LIBRARY_PATH``.//
-//Add ``export LD_LIBRARY_PATH="/usr/local/lib"`` to either your ``.bashrc`` or ``.profile``. You should now be able to start GF with C runtime.//
-
-
-=== Use GF server mode with C runtime ===
-
-- **What —**
-With this feature, ``gf -server`` mode is extended with new requests to call the C run-time
-system, e.g. ``c-parse``, ``c-linearize`` and ``c-translate``.
-
-- **How —**
-If you use cabal, run the following command:
-
-```
-cabal install -fc-runtime -fserver
-```
-from the top directory.
-
-If you use stack, add the following lines in the ``stack.yaml`` file:
-
-```
-flags:
-   gf:
-     c-runtime: true
-     server: true
-extra-lib-dirs:
-   - /usr/local/lib
-```
-
-and then run ``stack install``, also from the top directory.
-
+=== Python and Java bindings ===
 
+The C run-time system can also be used from Python and Java. Python and Java
+bindings are found in the ``src/runtime/python`` and ``src/runtime/java``
+directories, respecively. Compile them by following the instructions in
+the ``INSTALL`` files in those directories.
 
 == Compilation of RGL ==
 
 As of 2018-07-26, the RGL is distributed separately from the GF compiler and runtimes.
 
-To get the source, follow the previous instructions on [how to clone a repository with Git #getting-source].

+
+This is possible, but the procedure has not been automated.
+It involves using the cabal-rpm tool,
+
+```
+sudo dnf install cabal-rpm
+```
+
+and following the Fedora guide
+[How to create an RPM package http://fedoraproject.org/wiki/How_to_create_an_RPM_package].
+
+Under Fedora, Haskell executables are dynamically linked against other Haskell
+libraries, so ``.rpm`` packages for all Haskell libraries that GF depends on
+are required. Most of them are already available in the Fedora distribution,
+but a few of them might have to be built and distributed along with
+the GF ``.rpm`` package.
+When building ``.rpm`` packages for GF 3.4, we also had to build ``.rpm``s for
+``fst`` and ``httpd-shed``.
+
+== Running the testsuite ==
+
+**NOTE:** The test suite has not been maintained recently, so expect many
+tests to fail.
+%% // TH 2012-08-06
+
+GF has testsuite. It is run with the following command:
+```
+$ cabal test
+```
 The testsuite architecture for GF is very simple but still very flexible.
 GF by itself is an interpreter and could execute commands in batch mode.
 This is everything that we need to organize a testsuite. The root of the
-testsuite is the ``testsuite/`` directory. It contains subdirectories
-which themselves contain GF batch files (with extension ``.gfs``).
-The above command searches the subdirectories of the ``testsuite/`` directory
-for files with extension ``.gfs`` and when it finds one, it is executed with
-the GF interpreter. The output of the script is stored in file with extension ``.out``
-and is compared with the content of the corresponding file with extension ``.gold``, if there is one.
+testsuite is the testsuite/ directory. It contains subdirectories which
+themself contain GF batch files (with extension .gfs). The above command
+searches the subdirectories of the testsuite/ directory for files with extension
+.gfs and when it finds one it is executed with the GF interpreter.
+The output of the script is stored in file with extension .out and is compared
+with the content of the corresponding file with extension .gold, if there is one.
+If the contents are identical the command reports that the test was passed successfully.
+Otherwise the test had failed.
 
-Every time when you make some changes to GF that have to be tested,
-instead of writing the commands by hand in the GF shell, add them to one ``.gfs``
-file in the testsuite subdirectory where its ``.gf`` file resides and run the test.
-In this way you can use the same test later and we will be sure that we will not
-accidentally break your code later.
-
-**Test Outcome - Passed:** If the contents of the files with the ``.out`` extension
-are identical to their correspondingly-named files with the extension ``.gold``,
-the command will report that the tests passed successfully, e.g.
+Every time when you make some changes to GF that have to be tested, instead of
+writing the commands by hand in the GF shell, add them to one .gfs file in the testsuite
+and run the test. In this way you can use the same test later and we will be sure
+that we will not incidentaly break your code later.
 
+If you don't want to run the whole testsuite you can write the path to the subdirectory
+in which you are interested. For example:
 ```
- Running 1 test suites...
- Test suite gf-tests: RUNNING...
- Test suite gf-tests: PASS
- 1 of 1 test suites (1 of 1 test cases) passed.
+$ cabal test testsuite/compiler
 ```
-
-**Test Outcome - Failed:**  If there is a contents mismatch between the files
-with the ``.out`` extension and their corresponding files with the extension ``.gold``,
-the test diagnostics will show a fail and the areas that failed. e.g.
-
-```
-  testsuite/compiler/compute/Records.gfs: OK
-  testsuite/compiler/compute/Variants.gfs: FAIL
-  testsuite/compiler/params/params.gfs: OK
-  Test suite gf-tests: FAIL
-  0 of 1 test suites (0 of 1 test cases) passed.
-```
-
-The fail results overview is available in gf-tests.html which shows 4 columns:
-
-+ __Results__ - only areas that fail will appear. (Note: There are 3 failures in the gf-tests.html which are labelled as (expected). These failures should be ignored.)
-+ __Input__ - which is the test written in the .gfs file
-+ __Gold__ - the expected output from running the test set out in the .gfs file. This column refers to the contents from the .gold extension files.
-+ __Output__ - This column refers to the contents from the .out extension files which are generated as test output.
-After fixing the areas which fail, rerun the test command. Repeat the entire process of fix-and-test until the test suite passes before  submitting a pull request to include your changes.

+===What has been done with GF?===
+
+**Translation**: systems with any number of parallel languages, with input in one language and output in all the others.
+
+**Natural language generation** (NLG): translation from a formal language to natural languages.
+
+**Ontology verbalization** is a special case of NLG.
+
+**Language training**: grammar and vocabulary training systems.
+
+**Human-computer interaction**: natural language interfaces, spoken dialogue systems.
+
+**Linguistics**: comparisons between languages.
+
+
+
+===What parts does GF have?===
+
+A **grammar compiler**, used for compiling grammars to parsing, generation, and translation code. 
+
+A **run-time system**, used for parsing, generation and translation. The run-time system is available in several languages:
+Haskell, Java, C, C++, Javascript, and Python. The point with this is that you can include GF-based parsing and generation in 
+larger programs written in any of these languages.
+
+A **resource grammar library**, containing the morphology and basic syntax of currently 26 languages.
+
+A **web application toolkit**, containing server-side (Haskell) and client-side (Javascript) libraries.
+
+An **integrated development environment**, the GF-Eclipse plug-in.
+
+A **shell**, i.e. a command interpreter for testing and developing GF grammars. This is the program started by the command ``gf`` in a terminal.
+
+
+
+===Is GF open-source?===
+
+
+===Can I use GF for commercial applications?===
+
+Yes. Those parts of GF that you will need to distribute - the run-time system and the libraries - are licensed under LGPL and BSD; it's up to you to choose which. 
+
+
+
+===When was GF started?===
+
+
+===Where does the name GF come from?===
+
+GF = Grammatical Framework = LF + concrete syntax
+
+LF = Logical Framework
+
+Logical Frameworks are implementations of type theory, which have been built since the 1980's to support formalized mathematics. GF has its roots in
+type theory, which is widely used in the semantics of natural language. Some of these ideas were first implemented in ALF, Another Logical Framework,
+in 1992; the book //Type-Theoretical Grammar// (by A. Ranta, OUP 1994) has a chapter and an appendix on this. The first implementations did not have
+a parser, and GF proper, started in 1998, was an implementation of yet another LF together with concrete syntax supporting generation and parsing.
+Grammatical Framework was a natural name for this. We tried to avoid it in the beginning, because it sounded pretentious in its generality. But the
+name was just too natural to be avoided. 
+
+
+
+===Is GF backward compatible?===
+
+
+
+===Do I need Haskell to use GF?===
+
+No. GF is a language of its own, and you don't need to know Haskell. And if you download the GF binary, you don't need any Haskell tools. But if you want to
+become a GF developer, then it's better you install GF from the latest source, and then you need the GHC Haskell compiler to compile GF. But even then, you
+don't need to know Haskell yourself.

+<p>
+October 2011 for GF 3.3
+
+<p>
+
+<h1>Grammatical Framework Quick Start</h1>
+
+</center>
+
+This Quick Start shows a few examples of how GF can be used.
+We assume that you have downloaded and installed GF, so that
+the command <tt>gf</tt> works for you. See download and install
+instructions <a href="../download/index.html">here</a>.
+
+<h2>Want to try without downloading?</h2>
+
+<a href="../demos/phrasebook/">Using GF translation</a> with an existing grammar.
+
+<p>
+
+<a href="../demos/gfse/">Writing GF grammars</a> in the cloud, without installing GF.
+
+
+
+
+<h2>Using GF for translation and generation</h2>
+
+When you have downloaded and installed GF:
+<ol>
+<li> Copy the files
+<a href="../examples/tutorial/food/Food.gf"><tt>Food.gf</tt></a>,
+<a href="../examples/tutorial/food/FoodEng.gf"><tt>FoodEng.gf</tt></a>, and
+<a href="../examples/tutorial/food/FoodIta.gf"><tt>FoodIta.gf</tt></a>.
+Or go to <tt>GF/examples/tutorial/food/</tt>, if you have downloaded the
+GF sources.
+
+ <li> Start GF with the shell command (without the prompt <tt>$</tt>)
+<pre>
+  $ gf FoodIta.gf FoodEng.gf
+</pre>
+Alternatively, start GF with <tt>gf</tt> and give the GF command <tt>import FoodIta.gf FoodEng.gf</tt>.
+
+<li> <b>Translation</b>. Try your first translation by giving the GF command
+<pre>
+  parse "this cheese is very very Italian" | linearize
+</pre>
+Notice that the parser accept the tabulator for word completion.
+
+<li> <b>Generation</b>. Random-generate sentences in two languages:
+<pre>
+  generate_random | linearize
+</pre>
+
+<li> <b>Other commands</b>. Use the help command
+<pre>
+  help
+</pre>
+<li> <b>More examples</b>. Go to <tt>GF/examples/phrasebook</tt> or some other
+subdirectory of  <tt>GF/examples/</tt>. Or try a resource grammar by, for instance,
+<pre>
+  import alltenses/LangEng.gfo alltenses/LangGer.gfo
+
+  parse -lang=Eng "I love you" | linearize -treebank
+</pre>
+The resource grammars are found relative to the value of <tt>GF_LIB_PATH</tt>, which
+you may have to set; see <a href="../download/index.html">here</a> for instructions.
+
+
+
+</ol>
+
+
+
+<h2>Grammar development</h2>
+
+Add words to the <tt>Food</tt>
+grammars and try the above commands again. For instance, add the following lines:
+<pre>
+  Bread : Kind ;          -- in Food.gf
+  Bread = {s = "bread"} ; -- in FoodEng.gf
+  Bread = {s = "pane"} ;  -- in FoodIta.gf
+</pre>
+and start GF again with the same command. Now you can even translate
+<i>this bread is very Italian</i>.
+</ol>
+To lear more on GF commands and
+grammar development, go to the one of the tutorials:
+<ul>
+<li> <a href="tutorial/gf-tutorial.html">GF Tutorial</a>: older, more programmer-oriented
+<li> <a href="gf-lrec-2010.pdf">GF Resource Tutorial</a>: newer, more linguist-oriented
+</ul>
+To learn about how GF is used for easily writing grammars for 16 languages, consult the
+<ul>
+<li> <a href="../lib/doc/synopsis.html">GF Resource Grammar Library</a>.
+</ul>
+
+
+
+<h2>Run-time grammars and web applications</h2>
+
+GF has its own "machine language", PGF (Portable Grammar Format),
+which is recommended for use in applications at run time. To produce a PGF file from
+the two grammars above, do
+<pre>
+  gf -make FoodIta.gf FoodEng.gf
+  wrote Food.pgf
+</pre>
+You can use this in Haskell and Java programs, and also on web services, such as
+<ul>
+<li> the
+  <a href="http://cloud.grammaticalframework.org/minibar/minibar.html">minibar</a>
+  fridge magnets
+</ul>
+
+The quickest way to provide a GF web service is to start GF with the <tt>-server</tt> option:
+<pre>
+  $ gf -server
+  This is GF version 3.3
+  Built on linux/i386 with ghc-7.0, flags: interrupt server cclazy
+  Document root = /usr/local/share/gf-3.3/www
+  Starting HTTP server, open http://localhost:41296/ in your web browser.
+</pre>
+You can view it locally by pointing your
+browser to the URL shown. You can add your own <tt>.pgf</tt> grammar to the service by
+copying it over to the <tt>documentRoot</tt> directory. Just push "reload" in
+your browser after each such update.
+
+<p>
+
+To build more customized web application, consult the
+<a href="http://code.google.com/p/grammatical-framework/wiki/SideBar?tm=6">developer wiki</a>.
+
+
+<h2>User group</h2>
+
+You are welcome to join the <A HREF="http://groups.google.com/group/gf-dev">User Group</A>
+to get help and discuss GF-related issues!

+
+This is a quick reference on GF grammars. It aims to
+cover all forms of expression available when writing
+grammars. It assumes basic knowledge of GF, which
+can be acquired from the 
+[GF Tutorial http://www.grammaticalframework.org/doc/tutorial/gf-tutorial.html].
+Help on GF commands is obtained on line by the
+help command (``help``), and help on invoking
+GF with (``gf -help``).
+
+
+===A complete example===
+
+This is a complete example of a GF grammar divided
+into three modules in files. The grammar recognizes the
+phrases //one pizza// and //two pizzas//.
+
+File ``Order.gf``:
+```
+abstract Order = {
+cat 
+  Order ; 
+  Item ;
+fun 
+  One, Two : Item -> Order ;
+  Pizza : Item ;
+}
+```
+File ``OrderEng.gf`` (the top file):
+```
+--# -path=.:prelude
+concrete OrderEng of Order = 
+ open Res, Prelude in {
+flags startcat=Order ;
+lincat 
+  Order = SS ; 
+  Item  = {s : Num => Str} ;
+lin 
+  One it = ss ("one" ++ it.s ! Sg) ;
+  Two it = ss ("two" ++ it.s ! Pl) ;
+  Pizza  = regNoun "pizza" ;
+}
+```
+File ``Res.gf``:
+```
+resource Res = open Prelude in {
+param Num = Sg | Pl ;
+oper regNoun : Str -> {s : Num => Str} =
+  \dog -> {s = table {
+    Sg => dog ;
+    _  => dog + "s"
+    }
+  } ;
+}
+```
+To use this example, do
+```
+  % gf             -- in shell: start GF
+  > i OrderEng.gf  -- in GF: import grammar
+  > p "one pizza"  --        parse string
+  > l Two Pizza    --        linearize tree
+```
+
+
+
+===Modules and files===
+
+One module per file.
+File named ``Foo.gf`` contains module named
+``Foo``.
+
+Each module has the structure
+```
+moduletypename =   
+  Inherits **        -- optional
+  open Opens in      -- optional
+  { Judgements }   
+```
+Inherits are names of modules of the same type.
+Inheritance can be restricted:
+```
+  Mo[f,g],  -- inherit only f,g from Mo
+  Lo-[f,g]  -- inheris all but f,g from Lo
+```
+Opens are possible in ``concrete`` and ``resource``.
+They are names of modules of these two types, possibly
+qualified:
+```
+  (M = Mo), -- refer to f as M.f or Mo.f
+  (Lo = Lo) -- refer to f as Lo.f
+```
+Module types and judgements in them:
+```
+abstract A          -- cat, fun, def, data
+concrete C of A     -- lincat, lin, lindef, printname
+resource R          -- param, oper
+
+interface I         -- like resource, but can have
+                       oper f : T without definition
+instance J of I     -- like resource, defines opers
+                       that I leaves undefined
+incomplete          -- functor: concrete that opens 
+ concrete CI of A =    one or more interfaces
+  open I in ...
+concrete CJ of A =  -- completion: concrete that
+  CI with              instantiates a functor by
+    (I = J)            instances of open interfaces
+``` 
+The forms 
+``param``, ``oper`` 
+may appear in ``concrete`` as well, but are then
+not inherited to extensions.
+
+All modules can moreover have ``flags`` and comments.
+Comments have the forms
+```
+-- till the end of line
+{- any number of lines between -}
+--# used for compiler pragmas
+```
+A ``concrete`` can be opened like a ``resource``.
+It is translated as follows:
+```
+cat C          --->  oper C : Type = 
+lincat C = T           T ** {lock_C : {}}
+
+fun f : G -> C --->  oper f : A* -> C* = \g -> 
+lin f = t              t g ** {lock_C = <>}          
+```
+An ``abstract`` can be opened like an ``interface``.
+Any ``concrete`` of it then works as an ``instance``.
+
+
+
+===Judgements===
+
+```
+cat C               -- declare category C
+cat C (x:A)(y:B x)  -- dependent category C
+cat C A B           -- same as C (x : A)(y : B)
+fun f : T           -- declare function f of type T
+def f = t           -- define f as t
+def f p q = t       -- define f by pattern matching
+data C = f | g      -- set f,g as constructors of C
+data f : A -> C     -- same as 
+                       fun f : A -> C; data C=f
+
+lincat C = T        -- define lin.type of cat C
+lin f = t           -- define lin. of fun f
+lin f x y = t       -- same as lin f = \x y -> t
+lindef C = \s -> t  -- default lin. of cat C
+printname fun f = s -- printname shown in menus
+printname cat C = s -- printname shown in menus
+printname f = s     -- same as printname fun f = s
+
+param P = C | D Q R -- define parameter type P 
+                       with constructors
+                       C : P, D : Q -> R -> P
+oper h : T = t      -- define oper h of type T
+oper h = t          -- omit type, if inferrable
+
+flags p=v           -- set value of flag p
+```
+Judgements are terminated by semicolons (``;``).
+Subsequent judgments of the same form may share the
+keyword:
+```
+cat C ; D ;         -- same as cat C ; cat D ;
+```
+Judgements can also share RHS:
+```
+fun f,g : A         -- same as fun f : A ; g : A
+```
+
+
+===Types===
+
+Abstract syntax (in ``fun``):
+```
+C                -- basic type, if cat C
+C a b            -- basic type for dep. category
+(x : A) -> B     -- dep. functions from A to B
+(_ : A) -> B     -- nondep. functions from A to B
+(p,q : A) -> B   -- same as (p : A)-> (q : A) -> B
+A -> B           -- same as (_ : A) -> B
+Int              -- predefined integer type
+Float            -- predefined float type
+String           -- predefined string type
+```
+Concrete syntax (in ``lincat``):
+```
+Str              -- token lists
+P                -- parameter type, if param P
+P => B           -- table type, if P param. type
+{s : Str ; p : P}-- record type
+{s,t : Str}      -- same as {s : Str ; t : Str}
+{a : A} **{b : B}-- record type extension, same as  
+                    {a : A ; b : B}
+A * B * C        -- tuple type, same as
+                    {p1 : A ; p2 : B ; p3 : C}
+Ints n           -- type of n first integers
+```
+Resource (in ``oper``): all those of concrete, plus
+``` 
+Tok              -- tokens (subtype of Str)
+A -> B           -- functions from A to B
+Int              -- integers
+Strs             -- list of prefixes (for pre)
+PType            -- parameter type
+Type             -- any type
+```
+As parameter types, one can use any finite type:
+``P`` defined in ``param P``,
+``Ints n``, and record types of parameter types.
+
+
+
+===Expressions===
+
+Syntax trees = full function applications
+```
+f a b              -- : C if fun f : A -> B -> C
+1977               -- : Int
+3.14               -- : Float
+"foo"              -- : String
+```
+Higher-Order Abstract syntax (HOAS): functions as arguments:
+```
+F a (\x -> c)      -- : C if a : A, c : C (x : B), 
+                      fun F : A -> (B -> C) -> C
+```
+Tokens and token lists
+```
+"hello"            -- : Tok, singleton Str
+"hello" ++ "world" -- : Str
+["hello world"]    -- : Str, same as "hello" ++ "world"
+"hello" + "world"  -- : Tok, computes to "helloworld"
+[]                 -- : Str, empty list
+```
+Parameters
+```
+Sg                   -- atomic constructor
+VPres Sg P2          -- applied constructor
+{n = Sg ; p = P3}    -- record of parameters
+```
+Tables
+```
+table {              -- by full branches
+  Sg => "mouse" ;
+  Pl => "mice"
+  }
+table {              -- by pattern matching
+  Pl => "mice" ;
+  _  => "mouse"      -- wildcard pattern
+  }
+table {               
+  n => regn n "cat"  -- variable pattern 
+  }
+table Num {...}      -- table given with arg. type
+table ["ox"; "oxen"] -- table as course of values
+\\_ => "fish"        -- same as table {_ => "fish"} 
+\\p,q => t           -- same as \\p => \\q => t
+
+t ! p                -- select p from table t
+case e of {...}      -- same as table {...} ! e 
+```
+Records
+```
+{s = "Liz"; g = Fem} -- record in full form
+{s,t = "et"}         -- same as {s = "et";t= "et"}
+{s = "Liz"} **       -- record extension: same as
+  {g = Fem}             {s = "Liz" ; g = Fem}
+
+<a,b,c>        -- tuple, same as {p1=a;p2=b;p3=c}
+```
+Functions
+```
+\x -> t            -- lambda abstract
+\x,y -> t          -- same as \x -> \y -> t
+\x,_ -> t          -- binding not in t
+```
+Local definitions
+```
+let x : A = d in t -- let definition
+let x = d in t     -- let defin, type inferred
+let x=d ; y=e in t -- same as 
+                      let x=d in let y=e in t
+let {...} in t     -- same as let ... in t
+
+t where {...}      -- same as let ... in t
+```
+Free variation
+```
+variants {x ; y}     -- both x and y possible
+variants {}          -- nothing possible
+```
+Prefix-dependent choices
+```
+pre {"a" ; "an" / v} -- "an" before v, "a" otherw.
+strs {"a" ; "i" ;"o"}-- list of condition prefixes
+```
+Typed expression
+```
+<t:T>                -- same as t, to help type inference
+```
+Accessing bound variables in ``lin``: use fields ``$1, $2, $3,...``. 
+Example:
+```
+fun F : (A : Set) -> (El A -> Prop) -> Prop ; 
+lin F A B = {s = ["for all"] ++ A.s ++ B.$1 ++ B.s}
+```
+
+
+===Pattern matching===
+
+These patterns can be used in branches of ``table`` and
+``case`` expressions. Patterns are matched in the order in
+which they appear in the grammar.
+```
+C                 -- atomic param constructor
+C p q             -- param constr. applied to patterns
+x                 -- variable, matches anything
+_                 -- wildcard, matches anything
+"foo"             -- string
+56                -- integer
+{s = p ; y = q}   -- record, matches extensions too
+<p,q>             -- tuple, same as {p1=p ; p2=q}
+p | q             -- disjunction, binds to first match
+x@p               -- binds x to what p matches
+- p               -- negation
+p + "s"           -- sequence of two string patterns
+p*                -- repetition of a string pattern
+```
+
+===Sample library functions===
+
+```
+-- lib/prelude/Predef.gf
+drop   : Int -> Tok -> Tok   -- drop prefix of length
+take   : Int -> Tok -> Tok   -- take prefix of length
+tk     : Int -> Tok -> Tok   -- drop suffix of length
+dp     : Int -> Tok -> Tok   -- take suffix of length
+occur  : Tok -> Tok -> PBool -- test if substring
+occurs : Tok -> Tok -> PBool -- test if any char occurs
+show   : (P:Type) -> P ->Tok -- param to string
+read   : (P:Type) -> Tok-> P -- string to param
+toStr  : (L:Type) -> L ->Str -- find "first" string
+
+-- lib/prelude/Prelude.gf
+param Bool = True | False
+oper
+  SS  : Type                   -- the type {s : Str}
+  ss  : Str -> SS              -- construct SS
+  cc2 : (_,_ : SS) -> SS       -- concat SS's
+  optStr : Str -> Str          -- string or empty
+  strOpt : Str -> Str          -- empty or string
+  bothWays : Str -> Str -> Str -- X++Y or Y++X 
+  init : Tok -> Tok            -- all but last char
+  last : Tok -> Tok            -- last char
+  prefixSS : Str -> SS -> SS
+  postfixSS : Str -> SS -> SS
+  infixSS : Str -> SS -> SS -> SS
+  if_then_else : (A : Type) -> Bool -> A -> A -> A
+  if_then_Str : Bool -> Str -> Str -> Str
+```
+
+
+===Flags===
+
+Flags can appear, with growing priority,
+- in files, judgement ``flags`` and without dash (``-``)
+- as flags to ``gf`` when invoked, with dash
+- as flags to various GF commands, with dash
+
+
+Some common flags used in grammars:
+```
+startcat=cat    use this category as default 
+
+lexer=literals  int and string literals recognized
+lexer=code      like program code
+lexer=text      like text: spacing, capitals
+lexer=textlit   text, unknowns as string lits
+
+unlexer=code    like program code
+unlexer=codelit code, remove string lit quotes
+unlexer=text    like text: punctuation, capitals
+unlexer=textlit text, remove string lit quotes
+unlexer=concat  remove all spaces

+```
+For the full set of values for ``FLAG``, 
+use on-line ``h -FLAG``.
+
+
+
+===File import search paths===
+
+Colon-separated list of directories searched in the
+given order: 
+```
+--# -path=.:../abstract:../common:prelude
+```
+This can be (in order of increasing priority), as
+first line in the file, as flag to ``gf``
+when invoked, or as flag to the ``i`` command.
+The prefix ``--#`` is used only in files.
+
+GF attempts to satisfy an ``import`` command by searching for the
+import filename in the above search paths, initially qualified
+relative to the current working directory. If the file is not found in
+that initial expansion, the search paths are re-qualified relative to
+the directories given in the ``GF_LIB_PATH`` environment variable. If
+``GF_LIB_PATH`` is not defined, its default value is
+``/usr/local/share/gf-3.9/lib`` (assuming you have GF version 3.9).
+
+If your GF resource grammar libraries are installed somewhere else,
+you will want to set ``GF_LIB_PATH`` to point there instead. In a
+pinch, you can point to the ``GF/lib/src/`` folder in your clone of
+the GF source code repository.
+
+Developers of resource grammars may find it useful to define multiple
+directories, colon-separated, in ``GF_LIB_PATH``.
+
+
+===Alternative grammar formats===
+
+**Old GF** (before GF 2.0): 
+all judgements in any kinds of modules,
+division into files uses ``include``s.
+A file ``Foo.gf`` is recognized as the old format
+if it lacks a module header. 
+
+**Context-free** (file ``foo.cf``). The form of rules is e.g.
+```
+Fun. S ::= NP "is" AP ;
+```
+If ``Fun`` is omitted, it is generated automatically. 
+Rules must be one per line. The RHS can be empty.
+
+**Extended BNF** (file ``foo.ebnf``). The form of rules is e.g.
+```
+S ::= (NP+ ("is" | "was") AP | V NP*) ;
+```
+where the RHS is a regular expression of categories
+and quoted tokens: ``"foo", CAT, T U, T|U, T*, T+, T?``, or empty.
+Rule labels are generated automatically.
+
+
+**Probabilistic grammars** (not a separate format).
+You can set the probability of a function ``f`` (in its value category) by
+```
+--# prob f 0.009
+```
+These are put into a file given to GF using the ``probs=File`` flag
+on command line. This file can be the grammar file itself.
+
+**Example-based grammars**  (file ``foo.gfe``). Expressions of the form
+```
+in Cat "example string"
+```
+are preprocessed by using a parser given by the flag 
+```
+--# -resource=File
+```
+and the result is written to ``foo.gf``.

-### Notes
-
-The Windows package is installed by just unpacking it anywhere. You will
-probably need to set the `PATH` and `GF_LIB_PATH` environment variables,
-see Inari's notes on [Installing GF on Windows](http://www.grammaticalframework.org/~inari/gf-windows.html#toc3).
-
-The Ubuntu `.deb` packages should work on Ubuntu 16.04 and 18.04 and
-similar Linux distributions. The `.deb` packages were updated
-to version 3.10-2 after the release of GF 3.10.
-(Because of a packaging bug the Resource Grammar Library was missing
-in the 3.10-1 packages.)
-
-<!-- The Raspbian `.deb` package was created on a Raspberry Pi 3 and will
-probably work on other ARM-based systems running Debian 9 (stretch) or
-similar Linux distributions. -->
-
-The packages for macOS (Mac OS X) should work on at least 10.13 and
-10.14 (High Sierra and Mojave)
-
-<!-- The Mac OS and Linux `.tar.gz` packages are designed to be installed in
-`/usr/local`. You can install them in other locations, but then you need
-to set the `GF_LIB_PATH` environment variable:
-
-```
-export GF_LIB_PATH=/usr/local/share/gf-3.10/lib
-```
-
-where `/usr/local` should be replaced with the path to the location
-where you unpacked the package. -->
-
-## Installing the latest release from source
-
-[GF is on Hackage](http://hackage.haskell.org/package/gf), so under
-normal circumstances the procedure is fairly simple:
-
-1.  Install a recent version of the [Haskell
-    Platform](http://hackage.haskell.org/platform) (see note below)
-2.  `cabal update`
-3.  On Linux: install some C libraries from your Linux distribution (see note below)
-4.  `cabal install gf`
-
-This installs the GF executable and Haskell libraries, but **does not include the RGL**.
-
-You can also download the source code release from [GitHub](https://github.com/GrammaticalFramework/gf-core/releases),
-and follow the instructions below under **Installing from the latest developer source code**.
-
-### Notes
-
-**Installation location**
-
-The above steps installs GF for a single user. The executables are put
-in `$HOME/.cabal/bin` (or, with recent versions of the Haskell platform
-on Mac OS X, in `$HOME/Library/Haskell/bin`), so it is a good idea to
-put a line in your `.bash_profile` or `.profile` to add that directory
-to you path:
-
-```
-PATH=$HOME/.cabal/bin:$PATH
-```
-
-or
-
-```
-PATH=$HOME/Library/Haskell/bin:$PATH
-```
-
-**Build tools**
-
-In order to compile GF you need the build tools **Alex** and **Happy**.
-These can be installed via Cabal, e.g.:
-
-```
-cabal install alex happy
-```
-
-or obtained by other means, depending on your OS.
-
-**Haskeline**
-
-GF uses [`haskeline`](http://hackage.haskell.org/package/haskeline), which
-on Linux depends on some non-Haskell libraries that won't be installed
-automatically by cabal, and therefore need to be installed manually.
-Here is one way to do this:
-
-- On Ubuntu: `sudo apt-get install libghc-haskeline-dev`
-- On Fedora: `sudo dnf install ghc-haskeline-devel`
-
-**GHC version**
-
-The GF source code has been updated to compile with GHC 8.4.
-Using older versions of GHC (e.g. 8.2, 8.0 and 7.10) should still work too.
-
-## Installing from the latest developer source code
-
-If you haven't already, clone the repository with:
-
-```
-git clone https://github.com/GrammaticalFramework/gf-core.git
-```
-
-If you've already cloned the repository previously, update with:
-
-```
-git pull
-```
-
-Then install with:
-
-```
-cabal install
-```
-
-or, if you're a Stack user:
-
-```
-stack install
-```
-
-The above notes for installing from source apply also in these cases.
-For more info on working with the GF source code, see the
-[GF Developers Guide](../doc/gf-developers.html).
-
-## Installing the RGL from source
-
-To install the RGL from source,
-you can download a release from [GitHub](https://github.com/GrammaticalFramework/gf-rgl/releases)
-or get the latest version by cloning the repository:
-
-```
-git clone https://github.com/GrammaticalFramework/gf-rgl.git
-```
-
-In both cases, once you have the RGL sources you can install them by running:
-
-```
-make
-```
-
-in the RGL folder.
-This assumes that you already have GF installed.
-For more details about building the RGL, see the [RGL README](https://github.com/GrammaticalFramework/gf-rgl/blob/master/README.md).
-
-## Installing the Python bindings from PyPI
-
-The Python library is available on PyPI as `pgf`, so it can be installed using:
-
-```
-pip install pgf
-```
-
-We provide binary wheels for Linux and OSX (with Windows missing so far), which 
-include the C runtime and a ready-to-go.  If there is no binary distribution for
-your platform, this will install the source tarball, which will attempt to build 
-the binding during installation, and requires the GF C runtime to be installed on
-your system.

-
-**GF 3.11** was released on 25 July 2021.
-
-What's new? See the [release notes](release-3.11.html).
-
-#### Note: GF core and the RGL
-
-The following instructions explain how to install **GF core**, i.e. the compiler, shell and run-time systems.
-Obtaining the **Resource Grammar Library (RGL)** is done separately; see the section at the bottom of this page.
-
----
-
-## Installing from a binary package
-
-Binary packages are available for Debian/Ubuntu, macOS, and Windows and include:
-
-- GF shell and grammar compiler
-- `gf -server` mode
-- C run-time system
-- Java & Python bindings to the C run-time system
-
-Unlike in previous versions, the binaries **do not** include the RGL.
-
-[Binary packages on GitHub](https://github.com/GrammaticalFramework/gf-core/releases/tag/3.11)
-
-#### Debian/Ubuntu
-
-There are two versions: `gf-3.11-ubuntu-18.04.deb` for Ubuntu 18.04 (Cosmic), and `gf-3.11-ubuntu-20.04.deb` for Ubuntu 20.04 (Focal).
-
-To install the package use:
-
-```
-sudo apt-get install ./gf-3.11-ubuntu-*.deb
-```
-
-<!-- The Ubuntu `.deb` packages should work on Ubuntu 16.04, 18.04 and similar Linux distributions. -->
-
-#### macOS
-
-To install the package, just double-click it and follow the installer instructions.
-
-The packages should work on at least Catalina and Big Sur.
-
-#### Windows
-
-To install the package, unpack it anywhere.
-
-You will probably need to update the `PATH` environment variable to include your chosen install location.
-
-For more information, see [Using GF on Windows](https://www.grammaticalframework.org/~inari/gf-windows.html) (latest updated for Windows 10).
-
-## Installing from Hackage
-
-_Instructions applicable for macOS, Linux, and WSL2 on Windows._
-
-[GF is on Hackage](http://hackage.haskell.org/package/gf), so under
-normal circumstances the procedure is fairly simple:
-
-```
-cabal update
-cabal install gf-3.11
-```
-
-### Notes
-
-**GHC version**
-
-The GF source code is known to be compilable with GHC versions 7.10 through to 8.10.
-
-**Obtaining Haskell**
-
-There are various ways of obtaining Haskell, including:
-
-- ghcup
-    1.  Install from https://www.haskell.org/ghcup/
-    2.  `ghcup install ghc 8.10.4`
-    3.  `ghcup set ghc 8.10.4`
-- Haskell Platform https://www.haskell.org/platform/
-- Stack https://haskellstack.org/
-
-
-**Installation location**
-
-The above steps install GF for a single user.
-The executables are put in `$HOME/.cabal/bin` (or on macOS in `$HOME/Library/Haskell/bin`),
-so you might want to add this directory to your path (in `.bash_profile` or similar):
-
-```
-PATH=$HOME/.cabal/bin:$PATH
-```

-GF uses [`haskeline`](http://hackage.haskell.org/package/haskeline), which
-on Linux depends on some non-Haskell libraries that won't be installed
-automatically by Cabal, and therefore need to be installed manually.
-Here is one way to do this:
-
-- On Ubuntu: `sudo apt-get install libghc-haskeline-dev`
-- On Fedora: `sudo dnf install ghc-haskeline-devel`
-
-## Installing from source code

-stack install
-```
-
-<!--The above notes for installing from source apply also in these cases.-->
-For more info on working with the GF source code, see the
-[GF Developers Guide](../doc/gf-developers.html).
-
-For macOS Sequoia, you need to downgrade the LLVM package, see instructions [here](https://github.com/GrammaticalFramework/gf-core/issues/172#issuecomment-2599365457).
-
-## Installing the Python bindings from PyPI
-
-The Python library is available on PyPI as `pgf`, so it can be installed using:
-
-```
-pip install pgf

----
-
-## Installing the RGL from a binary release
-
-Binary releases of the RGL are made available on [GitHub](https://github.com/GrammaticalFramework/gf-rgl/releases).
-In general the steps to follow are:
-
-1. Download a binary release and extract it somewhere on your system.
-2. Set the environment variable `GF_LIB_PATH` to point to wherever you extracted the RGL.
-
-## Installing the RGL from source

-
-## What's new
-
-In this release, the GF "core" (compiler and runtimes) and RGL have been split into separate repositories.
-The binary packages on the downloads page contain both GF and the RGL, but the sources are now separate:
-[gf-core](https://github.com/GrammaticalFramework/gf-core) and
-[gf-rgl](https://github.com/GrammaticalFramework/gf-rgl).
-
-Over 300 changes have been pushed to GF and over 600 changes have been made to the RGL
-since the release of GF 3.9 in August 2017.
-
-## General
-
-- Travis integration:
-GF [![Build Status](https://travis-ci.org/GrammaticalFramework/gf-core.svg?branch=master)](https://travis-ci.org/GrammaticalFramework/gf-core) and
-RGL [![Build Status](https://travis-ci.org/GrammaticalFramework/gf-rgl.svg?branch=master)](https://travis-ci.org/GrammaticalFramework/gf-rgl)
-- A lot of bug fixes and repository cleanup, including things moved to new repositories:
-    - [Phrasebook](https://github.com/GrammaticalFramework/gf-contrib/tree/master/phrasebook)
-    - [Wide coverage translator](https://github.com/GrammaticalFramework/wide-coverage)
-    - [Mobile apps](https://github.com/GrammaticalFramework/gf-offline-translator)
