=head1 DESCRIPTION
B<iosock.pl> is a small example client for LCDd, the lcdproc server.
It tries to ping the servers given as parameters and displays on the LCD
whether they are reachable or not.
If no hosts are given as parameters a built-in list of default machines will be checked.

Connect to the LCDd daemon at host I<server> instead of the default C<localhost>.
=item B<-p> I<port>
Use port I<port> when connecting to the LCDd server instead of the default
LCDd port C<13666>.
=item B<-P> I<ping>
Use I<ping> as the command to check whether the remote hosts are reachable
instead of the default C<ping>.
Any I<ping> given using this options must understand the C<-c 1>
command line option of the default C<ping>.
=item B<-h>
Display a short help page and exit.
=item B<-V>
Display iosock.pl's version number and exit.
