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.
Turns out, all of our executables shared the same sort of

the yaml package. This package makes that process super
trivial.
