We do a lot of end-to-end testing and for that reason it really helps
to have an API which brings up dev_appserver for you, or deploys an
app, or configures the DOS settings, or gives you a pony. Now we are
probably not the only ones in App Engine land who would use such a
tool, so why not make it open source? I couldn't think of a reason so
here it is:

Beware though, I tagged it pre-alpha. It is lacking Java, Go, and
Fortran support, will benefit from user input, and does not give away
ponies, yet.
If you have feedback, bugs to file, or code to contribute, head over
to http://code.google.com/p/gaedriver/. Oh and there is also a
separate mailing list http://groups.google.com/group/gaedriver, too.
happy testing,
robert
