ncurses is proving too difficult to setup, so I'm working on a new library called charm. The C code works by itself, but I can't compile a Haskell wrapper for it. While the tutorials at HaskellWiki are helpful, they're outdated. Argh! The docs say that -#include pragmas no longer work, but fail to explain how to load code without them. Suffice to say I have no recourse but trial and error.
