Given that the automated part of the porting is a one-time thing (followed
by lots of hand-work). Using a lexer/parser/grammar and creating the needed
code-emitter seems like overkill. It seems to me that it would be less work
to write some regex-based Ruby scripts to handle the first pass.

Ruby/DL does sound like a good way to go.
