-This will install python-virtualenv into `/usr/local`. If you do not have
-write permission to `/usr/local`, you will need to run `sudo
-./install.sh` instead. You can install to a different prefix by
-setting the `PREFIX` environment variable.

-To update python-virtualenv after it has been installed, run `git pull` in
-your cloned copy of the repository, then re-run the install script.
