The "Software" is the Diversity University eDUcore MOO Database and associated 
components. A "MOO Database" is a Multi-user-domain Object Oriented ("MOO") 
database that when accessed by a MOO Server can be used to simulate a virtual 
reality world. A "MOO Server" is software that interprets a MOO Database, and 
performs those functions on the machine on which it runs to allow users to 
access a virtual world simulated by the MOO. Together a MOO Database and a MOO 
Server comprise a "MOO System." The "Documentation" is the user documentation, 
manuals, instructions or descriptions relating to the Software that DUETS, 
Inc. generally makes available.
