NAME
   Net::ClientServer - A client/server platform for IPC on localhost

VERSION
   version 0.0007

SYNOPSIS
   The minimum configuration (specify a port):

       my $platform = Net::ClientServer->new( port => 8020 );

       $platform->server_socket;

       ...

       if ( $platform->started ) { # Will attempt to connect to the listening socket
           $platform->client_socket;
       }

   Save server state to disk:

       $platform = Net::ClientServer->new( port => 8020, name => 'net-client-server' );
       # Server pid will be stored in $HOME/.net-client-server/pid
       # On daemonization, stderr will be outputted to $HOME/.net-client-server/stderr

   With a basic startup & serve/accept routine:

       my $port = 8020;
       $platform = Net::ClientServer->new(
           port => $port,
           start => sub {
               print STDERR "Server listening on $port\n";
           },
           serve => sub {
               my $client = shift; # The client socket
               $client->print( "Hello, World.\n" );
           },
       );

       $platform->start;

DESCRIPTION
   Net::ClientServer is a tool for implementing a basic client/server
   architecture using a single platform (particularly useful when doing IPC
   on the localhost). It is easily configured for daemonizing and
   maintaining state on disk (pidfile & stderr).

   The minimum configuration is very simple, requiring only a port number:

       my $platform = Net::ClientServer->new( port => 8020 );
       $platform->server_socket;

       ...

       $platform->client_socket;

USAGE
 $platform = Net::ClientServer->new( ... )
       port                The port to listen on/connect to

       host                The host to listen on/connect to, 'localhost' by default

       name                The name of the platform. If given without specifying the
                           home parameter, then pidfile and stderr will be put in
                           ~/.$name/

       home                The home directory for the platform. The pidfile and stderr will be
                           placed in this directory

       pidfile             The name of the pidfile, 'pid' by default.

       stderr              The name of file to output stderr to, 'stderr' by default

   If neither "home" nor "name" are given, then a pidfile and stderr file
   will not be generated

 $platform->start
   Start the server if it is not already running

 $platform->started
   Return true if the server is running. If a pidfile is available, then it
   will check to see that the process is running. If a pidfile is
   unavailable, or the process does not seem to be running, it will check
   to see if it can connect to the server
