[Haskell-cafe] Parsec Vs. src exts

[Roman Cheplyaka]

Hi Sean,

1. Please do not confuse haskell-src and haskell-src-exts. You should
   definitely use the latter. I also find it relatively well documented.
2. If your goal is to write a tool and not to write a Haskell parser as
   an exercise, then I would recommend haskell-src-exts. Another option
   is the GHC API.

If you have any particular questions or difficulties with these
libraries, feel free to post them here.

Roman
