47 | * A Critic can be disabled for a certain amount of time by giving it | |
48 | * the snooze command. Whereas most ControlMech's activate or deactivate | |
49 | * Critic's based on evidence of the Designer's state of mind, this | |
50 | * command allows the Designer to disable Critic's without stating any | |
51 | * reason. However, after a period of time, the critic may become | |
52 | * active again. We think this will often be convienent because | |
53 | * Designer's have a lot of tacit knowledge about their own state of | |
54 | * mind that is not worth making explicit. | |
