 - :remove: Remove a pip package
-- :user: User to run pip as, for using with virtualenv

 - :purge: Purge a pip package (this usually entails removing configuration files as well as the package itself).  With pip packages this behaves the same as `:remove`
 
 # Attribute Parameters
 
 - package_name: name attribute. The name of the pip package to install
 - version: the version of the package to install/upgrade.  If no version is given latest is assumed.
 - virtualenv: virtualenv environment to install pip package into
+- user: User to run pip as, for using with virtualenv
+- group: Group to run pip as, for using with virtualenv
 - options: Add additional options to the underlying pip package command
