Therefore, the file was renamed to an # importable python file, and forwarding python files are introduced with the old file names for full # compatibility. # * A bit of code rearranging and cleanup was necessary for that goal, but I hope the original parts are still # recognizable, as I tried to keep all this refactoring as less, as possible and sense-making, but did not do # the full clean-codish refactoring. Keeping the classes in one file is part of that refactoring-omittance. # * There is some initialization code executed in the classes not needed, if not imported. This is nagging me # somehow, but it is acceptable, as we do not need to save every processor cycle, here :) # * Have fun! import argparse import os import re import sys import time from array import array from datetime import datetime __version = "0.13" class SimpleTextAndIcons: font_11x44 = ( #
