     def produce_all_files(base):
         for root, dirs, files in os.walk(base):
             for r in files:
                 yield os.path.join(root, r)
             ### possibly also (but I'd only go for files)
             #for r in dirs:
             #    yield os.path.join(root, r)

     def findallfiles(base):
         return list(produce_all_files(base))
