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.
In the Unix shell there is no easy way to use a filter program to change the contents of a file in-place. For example, if you want to sort a file in place, this will not work:
sort < myfile > myfile
All that will get you is an empty myfile. This package gives you the rewrite program, so this will work:
rewrite myfile sort
