Well the simplest form is as I showed in my e-mail:

(err,stdout,stderr) = runcmd.run (['command','arg1','arg2', ... ])

An example where you need to pass stdin:

input="some string\n"
(err,stdout,stderr) = runcmd.run (['cmd','arg1',], stdin=input)

err is the return error code (int) and stdout and stderr are the strings
the result from the process's output, both strings.

There are some other features (or bugs probably) that you can get from
the source code itself.  I think at one time I wanted to be able to have
callbacks that would do something with stdout and stderr (in a
real-time, unbuffered way), but I have never used them and don't think
they work.
