+======Synopsis:======
+$[[levelctl]](LEVELS) \\
+$[[levelctl]](ADD //name//) \\
+$[[levelctl]](ALIAS //old-name// //new-name//) \\
+$[[levelctl]](LOOKUP //name//) \\

+$[[levelctl]](NORMALIZE //[[levels]]//)
+======Description:======
+The [[levelctl]] function allows you to add and look up levels for the client.
+The following operations are supported:
+^ Operation name ^ Operation function ^
+| LEVELS                          | Return a word list of the canonical names for all levels |
+| ADD //name//                    | Create a new level bit, and give it the canonical name //name//. |
+| ALIAS //old-name// //new-name// | Create a synonym (non-canonical name) for an existing level.  The //new-name// will be accepted in every place as a replacement for //old-name//.  This is suitable for translating level names.  |
+| LOOKUP //name//                 | Return the refnum of the level of the given //name//.  This number is only valid until the client exits.|
+| LOOKUP //number//               | Return the canonical name of the //number//th level.  This is useful in a loop to get each level name in order.|
+| NORMALIZE //level-description// | Convert a string containing level descriptions, of the sort "ALL,-OTHER" into the canonical form "PUBLICS,MSGS,NOTICES,WALLS,...." |
+======History:======
+The $levelctl() function first appeared in EPIC5-0.0.8.
