+Synopsis: A liberalised re-implementation of cpp, the C pre-processor.
+Description:
+    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.
