# This script will find all files greater than MIN_SIZE bytes
# whose mime type is one in the list and compressed it, saving
# the original file.  If the uncompressed file is newer than
# the compressed one, the compressed file will be overwritten
# by the newly compressed output.
# This is useful for web servers that want to send compressed
# content from an already-compressed file that matches a requested
# file.
