WAeUP permissions and roles
***************************

Permissions and roles used in a WAeUP portal.

:Test-Layer: unit


Before we can do something useful with roles and permissions, we have
to register them. This can be done simply by grokking the `waeup`
package:

    >>> import grok
    >>> grok.testing.grok('waeup')

We can get all roles defined in a WAeUP portal:

    >>> from waeup.permissions import getRoles
    >>> getRoles()
    ['waeup.PortalManager', 'waeup.PortalUser']
