# Pretty Printing

class Pretty p where

# Testing

prettyUsingInclude :: CTranslUnit -> Doc

Pretty print the given tranlation unit, but replace declarations from header files with `#include` directives.

The resulting file may not compile (because of missing `#define` directives and similar things), but is very usefull for testing, as otherwise the pretty printed file will be cluttered with declarations from system headers.
