Yes.  I was trying to point out that it is easy to support a language
using CEDET/Semantic by the existence of the 6 grammars which *I* did
not write.  The question I was trying to answer was if only super
hackers could support a language, so I was trying to point this out
that there are 6 regular hackers who have been successful.  There are
only two such hand crafted all Elisp super-parsers that I know of,
thus justifying the model I had proposed.  This, of course, assumes I
am a super-hacker.  I would rather think I'm just more familiar with
CEDET internals than most. :)

I, and other core CEDET developers have, as joakim pointed out above,
implemented many other grammars.  Missing from joakim's list are:

cedet/semantic/bovine/make.by
cedet/semantic/bovine/scheme.by
cedet/semantic/bovine/c.by     ; also has c++

plus a hand-written grammar for Elisp.  (I skipped the grammar
compilation step, and just typed in compiler compiler style output.)

There are also some regexp based grammars for html and texinfo, and
grammars for the grammar files.

If you have signed this stuff over, let me know and I'll move it.
