+purpose is to provide consistency between a development environemnt
+and production environment. This goal allows greater confidence that
+an application with passing tests in development will continue to
+function as expected in production.

+layer on top virtualenv. It should also support non-Python
+The main entry point to the xenv is the xe command. This command will
+allow using a specific environment when running commands.
