=============================Mutable History For Mercurial=============================This package supplies the ``evolve`` extension for Mercurial, whichprovides several commands to mutate history and deal with theresulting issues.It also: - enables the "changeset obsolescence" feature of Mercurial - issues several warning messages when trouble appears in your repository**This extension is experimental and not yet meant for production.**You can enable it by adding the line below to the ``extensions``section of your hgrc:: evolve = PATH/TO/mutable-history/hgext/evolve.pyWe recommend reading the documentation first.
