You also need to set OSGEO4W_ROOT_MSYS which should be an MSYS
compatible path.  Usually something like "/c/OSGeo4W" I think.

Sorry, I misunderstood the role of the setup command.  I assumed it
was a way of running the gui.  Disregard my comment.

I'd be in favor of just calling your program "apt" instead of o4w-apt -
I have the same problem with that being very ackward to type.

This could be a useful addition to the python package, making it easy for
other packages to create all the stub .bat files as part of their post install
step.  Perhaps you could file a ticket with the details, and I could update
the python package to include this, and the gdal-python package to use this.

PS. While I agree with Jeff that this apt utility will not be the primary
interface for new users, I think it is very handy for the not insignificant
group of us who are keen on commandline mechanisms.  I think the hardest
challenge is ensuring it integrates smoothly with other installation mechanisms
(like handling of postinstall steps, use of a common cache directory).
