10# VERSION
11# 1.0
12# PURPOSE
13# An implementation of a CSS compressor in Python. Written to
14# prepare development CSS to production ready CSS. Does the
15# following:
16# * Removes spaces intelligently
17# * Removes charset declarations
18# * Removes extra semicolons
19# * Flattens the file (tabs and line breaks)
20# USAGE
21# cmpcss site_dev.css > site_prod.css

24# restrictions.
25# WARRANTY
26# This program comes with NO warranty, real or implied. If it eats
27# your CSS, it's not my problem, you should have kept a backup.
