[Haskell-cafe] Wrapping external process communication in a nice API?

[Oleg Grenrus]

I wrote
https://github.com/phadej/cabal-extras/blob/master/cabal-docspec/src/System/Process/Interactive.hs
learning from what doctest, hlint and few other tools do.
They all (and you) seem to combine the process handling with the
specific process, coupling things which don't need to be.

That repository is under GPL, but if you find that module useful I can
relicense it.
