cleanup.py

#!/usr/bin/env python

# This is a helper program used to automatise some tasks related to distribution of this package.
# Removes all files with certain extensions in this directory and all subdirectories (5 levels deep)
# this is used to clear all temporary files and compiled code before packaging for distribution.
# The following extensions are being affected: ".py~", ".pyc", ".po~", ".pot~", ".txt~"
# and all __pycache__ directories including it's contents.
# rmcopy argument passed (ie. cleanup.py rmcopy) will also remove all copies of files (made on English locales)
# - removes all *copy).py files on top of earlier mentioned extensions.
# It also checks for any .mo files floating in .po directory and moves them to appropriate location in locale dir.
