  [ ... ]

CEDET does support many kinds of parsers.  It has two internal
parsers, one of which is wisent.  It has two regexp based parsers for
non-regular files like HTML.  It also uses exuberent ctags to parse
about 10 other langauges (in CVS).

If there is some external program that can it run and parse files, then
CEDET can use it.

It is also not just parsers.  If eclim has a tag database, it can use
that too, as the database backend is completely flexible.  It already
supports GNU Global and a couple other things.

I'd be happy to help someone do an integration with an external parser
if desired.
