For comparison, there's another LPeg-based C tokenizer at [1].  There
may be some issues using a C tokenizer as is on C++.  For example,
'::' is a C++ only token.  Peter's supports that (mine doesn't) though
doesn't appear to specially mark C++ keywords like 'try' and 'class'
for example.

Reliably parsing, not just lexing, C++ is no small feat.  gccxml was
discussed previously on this list [3].  See also [4].  Using the xml
output option from Doxygen may be a fairly accessible solution that's
good enough.
