Synopsis:
   set lastlog_level [[-]<level> [[-]<level> ...]]

Description:
   This setting controls the type(s) of information that EPIC will store
   in its lastlog buffer.  Any single message type, or any combination,
   may be used.  If a type is prepended with a '-', messages of that type
   are explicitly not saved (useful with the ALL type).  Message types
   may be abbreviated unambiguously.

Options:
   actions        public and private CTCP ACTION messages
   ctcp           CTCP messages (except ACTION and DCC)
   dcc            DCC messages
   msgs           MSG messages
   notes          NOTE messages (not supported on all servers)
   notices        NOTICE messages
   opnotes        operator broadcast messages
   public         public channel messages
   snotes         anything hooked by the SERVER_NOTICE hook
   userlog1 - 4   reserved for the user (available with XECHO)
   walls          WALL messages (deprecated, no servers support it)
   wallops        WALLOP messages
   crap           everything else (channel joins/parts, mode changes...)
   all            all of the above
   none           none of the above

Examples:
   To log everything except server and operator notices:
      /set lastlog_level all -opnotes -snotes

See Also:
   ctcp(1); dcc(1); msg(1); note(4); notice(1); on(5) server_notice; set(4)
   lastlog; wallop(3); window(4) lastlog_level; xecho(5)

Bugs:
   Message type names may only be abbreviated when including the type.  The
   full name must be given when excluding the type with a '-'.
