Net::Server::INET - Net::Server personality
=head1 SYNOPSIS
use base qw(Net::Server::INET);
sub process_request {
#...code...
}
Net::Server::INET->run();
=head1 DESCRIPTION
Please read the pod on Net::Server first. This module is a
personality, or extension, or sub class, of the Net::Server module.
This personality is intended for use with inetd. It offers no methods
beyond the Net::Server base class. This module operates by overriding
the pre_bind, bind, accept, and post_accept methods to let all socket
processing to be done by inetd.
