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.
