STATS with no option displays the values of the following variables:
MSM: Max number of server messages.
MSW: Max number of server messages with username-wildcards.
MUM: Max number of user messages.
MUW: Max number of user messages with username-wildcards.
MST: Max server time.
MSF: Note save frequency (checks for save only when an user register)
Notice that 'dynamic' mark after MSM means that if there are more
messages in the server than MSM, the current number of messages are
displayed instead of MSM.
Only one of this variables are displayed if specified.
You can change any of the stats by specifying new value after it.
RESET sets the stats to the same values which is set when starting the
server daemon if no note file exist. Notice that this stats are saved
in same file as the other messages.
Note that the STATS RESET command is only available to IRC operators.
