=head1 NAME

    evolve - board game frontend to AI::Evolve::Befunge


    evolve [-q|v|d] [-h host] [savefile]


This script is a frontend to the AI::Evolve::Befunge genetic
algorithm.  It sets up a board game instance, possibly loading
previous genetic data from a savefile (if given on the command line),
and starts running a new generation.

It will run until it is killed.


=head2 -q, --quiet

Enable quiet mode.  This will reduce the amount of output.

=head2 -v, --verbose

Enable verbose mode.  This will increase the amount of output.

=head2 -d, --debug

Enable debug mode.  This will increase the amount of output.

=head2 -h <hostname>, --hostname=<hostname>

Set the hostname to the specified value.  The default is to use the
output of the "hostname" shell command.

=head2 <savefile>

If specified, previous genetic data is read from this file.  You can
easily "fork" an existing population on a new host by reading its
