In the past, several Soar projects have been interested in the use of
multiple agents.  Up to this point, researchers have developed separate
systems by modifying their own copy of the existing Soar source.  While
helpful for the task at hand, these modifications were not added to the
mainstream Soar development.
 
Soar enables the user to create an arbitrary number of agents, each of which
has a separate memory.  All the agents run together within a single process
to minimize the overhead of communicating among the agents of the system.
(Consequently, this design does not add any additional operating system
requirements on the existing Soar code.)
 
If the user does not desire the use of multiple agents, then the use of Soar
will be the same as before (except for I/O code, see the next section).
