All of the contemporary languages (and at least one quite old [lisp]) are capable of re-working the output of CLang, so why the extra work to build an undocumented lib wrapper/implementation? This is the kind of text manipulation that '=bread+butter' for all of them. For that matter, I'm not clear on what is wrong with HTML as output which I believe that CLang exports?
Can you be more specific? Which output of clang are you referring to?
