It sounds straightforward to me. You'd write a batch file that automates the unzipping and zipping.
Hmm. I suppose. I've never tried that kind of thing, so that's why I didn't think about it.
It's something else to learn, but could be really useful. So do you mean writing a batch file so that it unzips the files, stages it and commits it? I'm not 100% sure how that would fit nicely with git stuff (plus, I tend to be lazy and use the GUI tools, but hey - I have always thought I should get used to the command line!).
(thanks for replying Ashley and R0J0hound by the way, much appreciated).
Could you point me towards some resources that would help me get my head round this?
