[cfe-dev] newbie wants to do round-trip, source to source C parsing

[Simon]

Hello! I discovered clang from this thread:
http://stackoverflow.com/questions/239722/ast-from-c-code

The example link in the thread describing how to perform 'source to
source' parsing and re-writing using clang doesn't work anymore :-(
Can anybody give links and/or hints and tips on how to do this and
where to start?

Thanks, Simon
