# Unreal Tournament File Tool for UT2004
#
# A cache-cleaner written in python for cygwin
#
# usage:
#
#   utft {command} {pattern}
# 
#   {command}:
#     ls      lists all files in the cache that match {pattern}
#     get     moves all files from the cache that match {pattern} to a directory 
#             named after the current time.
#     check   check whether everything in the Cache.ini is present in the cache
#             and report those missing
#     cleanup fix Cache.ini by removing entries for files that are missing.
#
#   {pattern}:
#     matches the start of the filename that would be created (e.g. 
#     VCTF-WS-StupdDeathRocket.ut2as rather than 20e9c02c809e098209580.uxx)
#     It is a python regexp rather than a nice shell glob.  And if you are typing
#     it in a cygwin shell, you'll need to add extra backslashes and stuff.
#
# Examples:
#
#   utft ls ONS-        lists all ONS maps
#   utft get .\*Stupid  gets all files with stupid in the name
#   utft get utx$       gets all .utx textures ($ matches end of name)
#
# Notes:
#
#   In order to avoid messing up your installation directories, the get command 
#   does not put the files into the right directories, but into a directory 
#   called Cleaned-YYYYMMDD-HHMMSS where YYYYMMDD-HHMMSS is the date and time
#   you ran the tool.  Under that directory, correct directories are used, so
#   you can simply drag-n-drop from there into the real dirs if you are 
#   convinced those files are the ones you really want.
#
# Example:
#
#   Before:
#     UT2004
#       +-Cache
#       |   +- 2309820348230948203.uxx   
#       |   +- 2340982034982438953.uxx   
#       +-Maps
#       +-Textures
#
#   After:
#     UT2004
#       +-Cache
#       +-Cleaned-20071114-233006
#       |   +-Maps
#       |   |   +-VCTF-TheCapOnTheMap.ut2
#       |   +-Textures
#       |       +-TexTuren.utx
#       +-Maps
#       +-Textures
#
#   Then, drag them:
#     UT2004
#       +-Cache
#       +-Cleaned-20071114-233006
#       +-Maps
#       |   +-VCTF-TheCapOnTheMap.ut2
#       +-Textures
#           +-TexTuren.utx
