+# cmpcss 
+#  Compress a CSS file in prepration for production use. 
+#   
+# AUTHOR 
+#       Michael Crute (mcrute@gmail.com)
+# DATE 
+#       16 June 2006
+# VERSION 
+#       1.0 
+# PURPOSE 
+#       An implementation of a CSS compressor in Python. Written to 
+#       prepare development CSS to production ready CSS. Does the
+#       following:
+#               * Removes spaces intelligently
+#               * Removes charset declarations
+#               * Removes extra semicolons
+#               * Flattens the file (tabs and line breaks)
+# USAGE 
+#       cmpcss site_dev.css > site_prod.css
