This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
This module provides facilities for building transactions out of
IO actions in such a way that, if one
IO action in a transaction throws an exception, the effects of previous actions will be undone.
