haskell-src-meta is a package originally by Matt Morrow for converting a parsed AST from haskell-src-exts to a TH AST for use in splices and quasiquoters. The last version Matt released before he disappeared from the Haskell community was 0.0.6, but by that time his library was already popular, so some community members eventually decided to take over maintenance of the package, keeping it up to date with the latest versions of TH etc.

I don't really view this as "my" package so if you want write access to the github repository, or you think you could do a better job as maintainer, just ask.
