description     The Glorious Glasgow Haskell Compilation System
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.
