+What is virtualenvwrapper
+virtualenvwrapper_ is a set of extensions to Ian Bicking's virtualenv_
+tool. The extensions include wrappers for creating and deleting
+virtual environments and otherwise managing your development workflow,
+making it easier to work on more than one project at a time without
+introducing conflicts in their dependencies.
+This new version uses a significantly rewritten version of the
+hook/callback subsystem to make it easier to share extensions. For
+example, released at the same time is virtualenvwrapper-emacs-desktop_,
+a plugin to switch emacs project files when you switch virtualenvs.
+Existing user scripts should continue to work as-written. Any failures
+are probably a bug, so please report them on the bitbucket
+tracker. Documentation for the new plugin system is available in the
+I also took this opportunity to change the name of the shell script
+containing most of the virtualenvwrapper functionality from
+virtualenvwrapper_bashrc to virtualenvwrapper.sh. This reflects the
+fact that several shells other than bash are supported (bash, sh, ksh,
+and zsh are all reported to work). You'll want to update your shell
+startup file after upgrading to 2.0.
+The work to create the plugin system was triggered by a couple of
+recent feature requests for environment templates and for a new
+command to create a sub-shell instead of simply changing the settings
+of the current shell. The new, more powerful, plugin capabilities will
+make it easier to develop these and similar features.
+I'm looking forward to seeing what the community comes up with. I
+especially want someone to write a plugin to start a copy of a
+development server for a Django project if one is found in a
+virtualenv. You'll get bonus points if it opens the home page of the
+server in a web browser.
