ghc6-prof 6.12.1-13ubuntu2 (i386 binary) in ubuntu natty

 Version 6 of the Glorious Glasgow Haskell Compilation system (GHC). GHC is
 a compiler for Haskell98.
 .
 Haskell is "the" standard lazy functional programming language. Haskell98
 is the current version of the language. The language definition and
 additional documentation can be found in the `haskell-doc' package.
 Alternatively, there is an online version at
 http://haskell.org/onlinereport/.
 .
 This package contains additional profiling libraries. They are only needed,
 if you want to take a closer look on where exactly your program burns CPU
 cycles.
