looper.php

<?php

/*
 * Script to loop through hex values and generate data!
 *
 * Sorry no documentation yet, but basically, this script is designed to loop
 *  through rgb values from a given starting point.
 *      php -f looper.php -- --red=0 --green=0 --blue=0
 *      php -f looper.php -- --red=0 --green=0 --blue=1
 *      php -f looper.php -- --red=0 --green=0 --blue=0
 *      php -f looper.php -- --red=0 --green=0 --blue=0 --red-max=2
 *
 * red-max indicates that the script should stop when the red loop gets to this value.
 *
 * In theory this script could be adapted to run in a map reduce kinda fashion,
 *  but that hasn't happened yet.
 *
 * I watch the log files with a command like this:
 *      watch --interval=1 --no-title tail -n2 looper*.log
