mach -- the generic command line interface framework that is behind the mach tool used to build Firefox -- now has its canonical home in mozilla-central, the canonical repository for Firefox. The previous home has been updated to reflect the change.

mach will continue to be released on PyPI and installable via pip install mach.

I made the change because keeping multiple repositories in sync wasn't something I wanted to spend time doing. Furthermore, Mozillians have been contributing a steady stream of improvements to the mach core recently and it makes sense to leverage Mozilla's familiar infrastructure for patch contribution.

This decision may be revisited in the future. Time will tell.
