good grief, the problem with haskell parsers is that there are so many to choose from !

i'm going to start with attoparsec.  one reason is that I really want to use the lazy interface just to see if i can and how it works.

Also as Chris said,  once i learn attoparsec I can learn the others, e.g. parsec, without too much trouble.

error trapping is not too critical (although i am going to need a line number).  the other slight complication is maintaining some sort of parse state- but i'll deal with that when i get to it which probably won't be for a while...

Thanks very much for all the suggestions !
