#
# This script is used to clean up files and folders that are not needed on your linux system
# Directories to clean are stored in an associative array with the key being the directory and the value being:
# a comma separated list of file or folder names and types.  These are compatible arguments for the
# find command.  The script will search for these files and folders and remove them.
#
# DATA LOSS WARNING: This script will remove files and folders from your system.  Please be careful with it.
# I accept no legal responsibility for any damage caused by using or misusing this script.  Change the configuration
# at your own risk.

# Put your directories that you want to autoclean by file or folder name and type here.
