Wow! I've never done this before, so I don't know what's traditionally
done to do monitoring. One idea is to have your program sleep for a
while, and then every once in a while, check to see if things in your
directory are changing. Here's some pseudocode:
dircontents = getDirContents()
newcontents = getDirContents()
if dircontents != newcontents:
dircontents = newcontents
This won't work unless we define getDirContents(), but that shouldn't be
too bad. You can do directory stuff with the 'os.path' module. From a
quick scanthrough, the 'dircache' module also looks useful for this stuff.
This looks like an interesting program! I hope this helps get you
