description	The Glorious Glasgow Haskell Compilation System (development version)
long_description	\
		The Glasgow Haskell Compiler is a robust,		\
		fully-featured, optimising compiler and interactive	\
		environment for Haskell 98, GHC compiles Haskell to	\
		either native code or C.  It implements numerous	\
		experimental language extensions to Haskell 98,		\
		for example: concurrency, a foreign language interface,	\
		multi-parameter type classes, scoped type variables,	\
		existential and universal quantification, unboxed	\
		types, exceptions, weak pointers, and so on.		\
		GHC comes with a generational garbage collector,	\
		and a space and time profiler.

#user_notes	All of the executables have the version as a suffix,	\
#		so you must invoke ghc-6.9 or ghci-6.9 or hsc2hs-6.9...	\
#		Not all of the files in /bin are different from the	\
#		production version, but it seems safer not to overwrite	\
#		the versions that are officially supported.

#bugs		GHC does not support DESTDIR. Instead, we install	\
#		everything into ${destroot}/${prefix}, and then fix up	\
#		the five scripts which actually have the installation	\
#		path hard coded.
