        !             2: 
        !             3: LON-CAPA has two basic types of Roles, {}``domain'' and {}``course''
        !             4: roles.
        !             5: 
        !             6: While LON-CAPA is a role based system, a {}``role'' is really a
        !             7: collection of {}``permissions'', such as {}``permission to post''
        !             8: or {}``permission to change student grades''. For a complete list
        !             9: of currently existing permissions, please consult \texttt{/home/httpd/lonTabs/rolesplain.tab}
        !            10: in a LON-CAPA install. For a complete definition of the various roles
        !            11: described below, consult the \texttt{/home/httpd/lonTabs/roles.tab},
        !            12: in conjunction with the \texttt{rolesplain.tab} file. 
        !            13: 
        !            14: Domain Administrators and Course Coordinators can create custom roles,
        !            15: so the following only discusses the roles that LON-CAPA ships with,
        !            16: and is not necessarily an exhaustive list, just the common ones. As
        !            17: a developer, it is generally better to look at the \emph{permissions}
        !            18: a user has when determining whether they can perform an action, rather
        !            19: then their specific role.

        !            31: roles for any course in the domain, so they do theoretically have
