# Changelog
# 1.00 - Initial version
# 1.10 - Added support for CBZ/CBR files
# 1.11 - Added support for ZIP/RAR extensions
# 1.20 - Comic optimizations! Split pages not target-oriented (landscape
# with portrait target or portrait with landscape target), add palette
# and other image optimizations from Mangle.
# WARNING: PIL is required for all image mangling!
#
# Todo:
# - Add gracefully exit for CBR if no rarfile.py and no unrar
# executable are found
# - Improve error reporting
#
# - recurse into dirtree for multiple comics
