Hi,
I am looking for Haskell libraries to do approximate string matching:

I need this to reduce a set of English word variants with spelling errors to
a single canonical dictionary entry.
Any libraries to work with spelling will also help.

If you want to implement some kind of publish/subscribe system over the

You can try to build it by adding '--constraint=hxt==9.0.\*' after

ranges to the package.
