[Boost-users] Spirit and CTTL

Ok, I didn't go to school for computer programming, so I never had experience with a "Compilers" class or anything related to lexing/parsing. But now I'm getting interested in it and have begun looking at some things. Spirit seems good, but it seems very weighty to work with. I was wondering if anyone has experiences with Spirit *and* CTTL and would be able to list for me some of the pros and cons of each. Spirit is, of course, a boost library and would be easier to find help and things of that nature, but CTTL seems to be a tad more lightweight (I'm not really sure). Thanks for any and all replies.
