Usage: screenwidth [#]

   Sets how many characters your client can display in one line (40-200).
   
Text within the game is wrapped at this value. We attempt to auto-detect this
from your mud client using a telnet option called NAWS, but not all clients
report this, or report it correctly.

The NAWS value shown when you first connect displays what your client has sent.
The screenwidth and screensize commands allow you to override those values.
