RubyToC has the following modules:

* Rewriter      - massages the sexp into a more consistent form.
* TypeChecker   - type inferencer for the above sexps.
* RubyToRubyC   - converts a ruby (subset) sexp to ruby interals C.
* RubyToAnsiC   - converts a ruby (subset) sexp to ANSI C.

and the following tools:

* translate.rb  - Translates a given file to C.
