# author : Brian Ernst
# python_version : 2.7.6
# python_version : 2.7.6 and 3.4.0
# =================================
# todo: have a backup feature, make sure files are moved to the recycle bin or a temporary file.
# todo: switch to faster method of calling p4 fstat on an entire directory and parsing it's output
# todo: add option of using send2trash
# todo: buffer output, after exceeding a certain amount print to the output.
# todo: allow logging output besides console output, or redirection altogether
