=head1 NAME

samplechat.pl - Show a basic Net::Server::Multiplex sample

=head SERVER SYNOPIS

    # To run this in background daemon mode, listening on port 2000, do:

    samplechat.pl --setsid=1 --log_file=/tmp/samplechat.log --pid_file=/tmp/samplechat.pid --port=2000

    # To turn off the daemon, do:

    kill `cat /tmp/samplechat.pid`;

=head CLIENT SYNOPIS

    # from a terminal type

    telnet localhost 2000

    # you will then be in a echo server.

=head DESCRIPTION

This example demonstrates some of the features of Net::Server::Multiplex
