I was looking through the AFKMUD 1.64 wizhelp for some reason that is now unknown to me, and I noticed the shipset command. I tried to see if there was a help for it, but there wasn't. So, I typed in "shipset" by itself and this came up:
Syntax: shipset create
Where is one of:
name owner vnum type fuel max_fuel
hull max_hull coords room flags
I get the fields name, owner, fuel, max_fuel, hull, max_hull, & coords, but that is it.
