Cpphs is a re-implementation of the C pre-processor that is both more
compatible with Haskell, and itself written in Haskell so that it can be
distributed with compilers.
This version of the C pre-processor is pretty-much feature-complete and
compatible with traditional (K&R) pre-processors. Additional features include:
a plain-text mode; an option to unlit literate code files; and an option to
turn off macro-expansion.
