+SUMMARY = "Modern, multi-threaded and extensible web server."
+DESCRIPTION = "The Rocket web server is a server designed to handle the increased \
+needs of modern web applications implemented in pure Python. It can serve WSGI \
+applications and static files. Rocket has the ability to be extended to handle \
+different types of networked request-response jobs. Rocket runs on cPython 2.5- 3.x \
+and Jython 2.5 (without the need to run through the 2to3 translation tool). Rocket \
+is similar in purpose to Cherrypy’s Wsgiserver but with added flexibility and concurrency."
