I'm thinking os.walk() could definitely be a big part of my solution,
but I need a little for info.  If I'm reading this correctly, os.walk()
just goes file by file and serves it up for your script to decide what
to do with each one.  Is that right?  So, for each file it found, I'd
have to decide if it met the criteria of the filetype I'm searching for
and then add that info to whatever datatype I want to make a little
list for myself?  Am I being coherent?

Something like:

for files in os.walk(top, topdown=False):
    for name in files:
         (do whatever to decide if criteria is met, etc.)

Does this look correct?
