07c56447 | 10 | * Generic menu system module. |
11 | * | |
12 | * Basically, we define an enormous tree structure which represents the | |
13 | * menu. Some extra pieces (ml_command, ma_doc) get thrown in so we can | |
14 | * also use the structure for a command-based system. | |
15 | * | |
16 | * By making the menu descriptions so general, we can ease porting to just | |
17 | * about anything. | |
