XThis is TinyMUD version 1.5.4, a user-extendible, multi-user adventure game.
X
XBasic commands:
X move/go <direction>
X get/take <thing>; drop/throw <thing>
X look; look <thing>; look <direction>
X say <message>; whisper <player> = <message>
X rob <player>; give <player> = <number of pennies>; kill <player>
X inventory
X help
X news
X @describe me = <description>
X @password <oldpassword>=<newpassword>
X page <player> --- tell player that you are looking for them (cost 1 penny)
X gripe <message> --- Complain to the management.
X home --- go home
XOther commands are available for extending the universe. Many of
Xthese commands cost pennies, which you can obtain in a number of ways.
XFull names of exits can be used in place of a go or move command. The
Xnames "me" and "here" are special; me means the current player, and
Xhere means the current player's location.
XMore information is available in the reference section of the Library,
Xnorth of the Temple.
XRemember, no matter how bad it gets, you can always go home.

XNotes to new administrators using small.db:
X
X1. There are four objects of type player in small.db: Wizard(#1),
XBeaker(#2), guy(#121), and Darooha(#203). As distributed, all have
Xthe password "potrzebie." Wizard is the administrative player; it is
Xthe only one that has its WIZARD bit set, and it owns most of the core
Xrooms. Beaker is included for testing. guy and Darooha own the
X"Eastward Ho" and "Bud's" adventures; if you want to leave these
Xsamples out, you can remove them using extract. Only the Wizard and
Xthe objects owned by the Wizard are really important...
X
X2. Small.db contains no unlinked exits; thus it will be impossible for
Xanybody who is not a WIZARD to connect new rooms to the core rooms.
XWhen TinyMUD was first started up on LANCELOT.AVALON.CS.CMU.EDU, the
XTown Square was given 9 unlinked exits (7 of the 8 cardinal directions
Xplus up and down) and was set to be LINK_OK; this allowed early
Xconstruction to take place in the neighborhood of the Town Square
Xwithout the need for administrative oversight.
X
XWhile this policy worked well during the early lifetime of the game,
Xas the database grew the immediate surroundings of the Town Square
Xbecame rather chaotic, and only a few of the directions exits from it
Xgot much use. It might be reasonable to build a more extensive Town
XCenter before allowing haphazard construction.
X
X--Jim Aspnes
X
XYou might want instead to get a copy of TinyBASE, a more logical and
Xcomplete basis for starting a new MUD.
