Qsync: Mercurial to MQ exporter
---------------------------------------------------------------------
People may have tools or co-workers that export to receive mutable history using
a versioned mq repository.
For this purpose you can use the ``qsync`` extension:
To enable the evolve extension use::
$ hg clone http://hg-dev.octopoid.net/hgwebdir.cgi/mutable-history/
$ mutable-history/iqsync-enable.sh >> ~/.hgrc
$ hg help qsync
