+OutputCompression
+=================
+
+Allows gzip output compression to clients that support it. Simple to use, just
+put after_filter :compress_output in your controller. Pulled out of the Google
+cache and packaged into plugin form, code originally hosted at
+http://www.tuxsoft.se/oss/rails/download/output_compression.rb.
