+This is the source tree for GHC, a compiler and interactive
+environment for the Haskell functional programming language.
+
+For more information, visit GHC's web site:
+
+ http://www.haskell.org/ghc/
+
+Information for developers of GHC can be found here:

+
+
+Getting the Source
+==================
+
+There are two ways to get a source tree:
+
+ 1. Download source tarballs
+ ---------------------------
+
+ The GHC source distribution comes in two parts:
+
+ ghc-<version>-src.tar.bz2
+ ghc-<version>-src-extralibs.tar.bz2
+
+ You only need the first one, which contains GHC itself and
+ the "core" libraries.
+
+ The extralibs package contains a bunch of optional libraries. If
+ you want, you can unpack this over the top of your source tree, and
+ these extra libraries will be built and installed automatically.
+ Make sure you unpack the extralibs package before running configure
+ (see below).
+
+ If you don't build extralibs now, you can add them later by building
+ and installing individual packages using Cabal.
+
+ 2. Get the source from darcs
+ ----------------------------
+
+ First get the GHC darcs repository:
+
+ $ darcs get http://darcs.haskell.org/ghc/
+
+ Then run the darcs-all script in that repository
+ to get the other repositories:
+
+ $ cd ghc
+ $ chmod +x darcs-all
+ $ ./darcs-all get
+
+ This grabs the "core" packages by default. To get the full set of
+ packages, instead say
+
+ $ ./darcs-all --extra get
+
+ This also downloads the libraries that are normally bundled in the
+ "extralibs" package (see above).
+
+
+Building & Installing
+=====================
+
+NB. you need GHC installed in order to build GHC, because the compiler
+is itself written in Haskell. It is possible to build GHC using just
+a C compiler, but we don't recommend this as the normal route. If you
+*really* want to do it this way, then see the Building Guide (link
+below).
+
+You also need a few other tools installed: Happy [4], Alex [5], and
+Haddock [6] (for building library documentation), and a good DocBook
+XML toolchain if you want to build the compiler documentation.
+
+Quick start: the following gives you a default build:
+
+ $ sh boot
