This really sounds good!

How is mach working on windows with pymake?

(Yes, you can tab complete test paths in your shell instead of going through some silly environment variable dance).

If you get lost:

$ ./mach help

(Try doing that with make!)

Read more about mach at [1].

I want to stress that mach is still in its infancy. It is currently only a fraction of what I want it to be. However, mach today is infinitely more than what it was yesterday: non-existent. That's progress. If you have a feature request or a work flow, please file a bug. Even better, contribute a patch! You only need to know beginner's Python to add new commands to mach.

I hope you enjoy using mach. I look forward to many new and exciting features in the near future.
