My problem might be close to this one. and I'm a python newbie, so...

I'm trying to make a python script to automate a makefile update
process. There are two different makefiles in version control system and
the second one needs the version number of the first one.

So first I make the correct system calls as above to check-out, update
and check-in the first makefile. But after the check-in :

        os.system(' put c:\something\foo.c ')

the version control system prints something like this :

        "version 1.5 of file foo.c was checked in."

The problem is that how do get the version number from the first
check-in, because it's needed in the second makefile update ?

Michael S. is talking something about "the output of the command" above.
Is that what I need and how do I "check out the commands module" ?
