+WHAT DOES IT DO?
+- Moves the checked out repository to a unique directory in the workspace
+
+REQUIREMENTS:
+- Drush
+- A web accessible URL for the pull request. The location of the docroot for
+  this URL should be specified with the -l option.
+- An existing Drupal 7 site with a site alias, and empty prefix line in the
+  database array in settings.php
+- A Jenkins job that checks out the Pull Request to 'new_pull_request' directory
+  inside the job workspace.
+
+OPTIONS:
+   -h      Show this message
+   -l      Location of the docroot where the site will be symlinked to. Note,
+           the Jenkins user must have write permissions to this directory.
+   -d      Defaults to 'http://default'. The domain name the site will be set up
+           at. Note, the site will be in a subdirectory of this domain using the
+           Pull Request ID, so if the Pull Request ID is 234, and you pass
+           https://www.example.com/foo, The site will be at
+           https://www.example.com/foo/234.
+   -a      The drush site alias for the source site to copy from.
+   -r      The path to drush. Defaults to drush.
+   -v      Verbose mode, passed to all drush commands.
