-===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.

-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

-
-===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
-unlexer=bind    remove spaces around "&+"
-
-optimize=all_subs  best for almost any concrete
-optimize=values    good for lexicon concrete
-optimize=all       usually good for resource
-optimize=noexpand  for resource, if =all too big
-```
-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``.

+
+**Features**
+
+- GF = GF shell and grammar compiler
+- S = `gf -server` mode
+- C = C run-time system
+- J/P = Java/Python binding to the C run-time system
+
+### 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 yum 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).

+title: GF 3.10 Release Notes
+date: 2 December 2018
+...
+
+## Installation
+
+See the [download page](index.html).
+
+## 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)
+    - [gftest](https://github.com/GrammaticalFramework/gftest)
+    - [gf-mode](https://github.com/GrammaticalFramework/gf-emacs-mode) for Emacs
+    - [RGL browser](https://github.com/GrammaticalFramework/rgl-source-browser) (live [here](http://www.grammaticalframework.org/~john/rgl-browser/))
+- A fresh look for the GF website.
+
+## GF compiler and run-time library
+
+- Extensive improvements in the C runtime and bindings to it from Python, Java, Haskell, C#
+- A GF shell which uses the C runtime
+- Better error messages
+- GF now has a Stack configuration file
+- The compiler source code has been updated for compatibility with GHC 8.4.3.
+- `GF_LIB_PATH` can now be `path1:path2:path3`, not just `path1`
+- Add TypeScript type definitions for `gflib.js`
+- New compiler/shell options
+    - added option `-output-format=java` for producing code for embedded grammars in Java
+    - `rf -paragraphs`
+    - `linearize -tabtreebank`
+    - A new function called `completions` is added in the Haskell runtime and used in PGFService. This makes the extraction of completions more platform independent
+
+## Resource Grammar Library
+
+- [Bash build script](https://github.com/GrammaticalFramework/gf-rgl/blob/master/Setup.sh), for building the RGL without Haskell
+- [Windows build script](https://github.com/GrammaticalFramework/gf-rgl/blob/master/Setup.bat), for building the RGL without Haskell on a regular Windows command shell
+- New languages:
+    - Basque
+    - Portuguese
+- Big progress with Arabic, Turkish, Persian
+- Introduction of `Extend` module to combine the functions of `Extra` and `Extensions` in a more disciplined way
+- Various fixes for several languages.
+- Various fixes in the translation dictionaries.
+
+## Apps and Cloud services
+
+- Sort list of public grammars by age by default
+- Browser compatibility fixes
+- Allow public grammars to be deleted in more cases
+- Show grammar comments in the list of public grammars

---   - If lang has coding=other, and -to_utf8 is in opts, from_other is applied first.
