[Ctags] new language support

[Doug M. <Douglas.Meyer@Sun.COM>]

Dear ctag-ers:

I'm only about an hour into looking at the Exuberant Ctags site, reading
about how to extend ctags, and building the source, so you could say I'm
a little new at this.  I am doing all this to be able to create ctags
for a new language.  This raises a couple questions right off the bat:

1. Is there a particular reason that yacc-based parsers aren't
    used for the various languages?  Wouldn't that be a straight-forward
    way to get the desired tokens?

2. Can the regexp implementation methodology be used when the language
    supports continuation lines?  Are there any existing examples of
    this that I can use as a model?

Thanks so much for the help.  I'm very confident there will be many
more questions down the road.

Blessings,
Doug
