From Tapestries MUCK
Pose is a simple built-in command for MUCKs. Its purpose is to depict an action. It is most commonly abbreviated to ':' (a single colon). Pose is limited to a single room.
For the purpose of the command lines entered, please assume the player entering the command is named Player.
Command line: pose wanders into the room, bows, and says 'Hello,' before wandering off. Result:
Player wanders into the room, bows, and says 'Hello,' before wandering off.
Command line: :tapdances on the ceiling! Result:
Player tapdances on the ceiling!
The pose command is a core command for any MUCK as far as basic interaction with others is concerned. Many MUCK-defined commands and the Say command can be replaced with pose, though in many cases it's more efficient for the MUCK to define the commands separately. Unlike some commands, pose sends the same post to both the entering player and the room at large.
