-$loncaparev - Version on current server (format: Major.Minor.Subrelease-datestamp)
-
-$interval (optional) - Time which may elapse (in s) between last check for content
-                       change in current course. (default: 600 s).
-
-Returns: an array; first element is:
-
-=over 4
-
-'switch' - if content updates mean user's session
-           needs to be switched to a server running a newer LON-CAPA version
-
-'update' - if course session needs to be refreshed (i.e., Big Hash needs to be reloaded)
-           on current server hosting user's session
-
-''       - if no action required.
-
-=back
-
-If first item element is 'switch':
-
-second item is $switchwarning - Warning message if no suitable server found to host session.
-
-third item is $switchserver - query string to append to /adm/switchserver containing lonHostID
-                              and current role.
-
-otherwise: no other elements returned.
