// documentation on http://about.psyc.eu/Create_Place
//
// place.gen was inspired by loc.h, a similar room generation system in
// the Nemesis mudlib. Nemesis itself being a legendary MUD based in
// Munich (http://www.nemesis.de). the innovation in this room generation
// approach is to use the #include to generate code rather than to define
// a series of macros and hope the user uses them the right way.
// of course these days you could do a room generator in -say- perl..
// or you could implement a mega do-everything room class which can then
// be configured at runtime by web interface or slash command. in fact
// standard.c is just that, only that it didn't get all that popular.
