+# This package provides symbolic links to the Glasgow Haskell Compiler, but
+# with the global package database restricted to only boot libraries.  This is
+# useful for building statically linked executables without interference from
+# the official haskell-* packages, which only offer dynamic libraries and
+# makes cabal hopelessly confused.
+#
+# To use this package, you just need to configure cabal
+# --with-compiler=/usr/share/ghc-pristine/bin/ghc
