Run one copy of the server and several copies of the application
program.

Usage of the server:

   perl DSMSvr.pl port_number debug_flag

where port_number is the TCP port number you wish to use, and debug_flag
is 'd' for debug, anything else for no debug.

Usage of an application, X.pl:

   perl X.pl server_machine port_number_ application_arguments

Start the server before the application.

Almost all the PerlDSM constructs are illustrated in the sample program,
AvgLdAvg.pl.

Shared variables are designated as shared via calls to tie().  The class
they are tied to, DSMScalar in the case of scalars, does the necessary
network communication, transparently to the programmer.
