I'm trying to start a process using Msys from a Python script on WinXP and can't figure it out.

Normally I'd assume it's something like:

msys.exe whatever.exe -arg1 -arg2

The above would launch "whatever.exe -arg1 -arg2" from msys.exe.

But because msys launches with a batch file, I can't figure out how to do that.

Is there a way to do this?
