installation and setup instructions.
+virtualenvwrapper is a set of shell *functions* defined in Bourne
+shell compatible syntax. It is tested under `bash`, `ksh`, and `zsh`.
+It may work with other shells, so if you find that it does work with a
+shell not listed here please let me know. If you can modify it to
+work with another shell, without completely rewriting it, send a pull
+request through the bitbucket project page. If you write a clone to
+work with an incompatible shell, let me know and I will link to it
+virtualenvwrapper is tested under Python 2.4 - 2.7.
