 * bubblefishymon
 *
 * Well, Hacks from bubblemon by timecop and Johan
 *
 * http://www.student.nada.kth.se/~d92-jwa/code/
 * http://www.ne.jp/asahi/linux/timecop/
 *
 * Basically putting timecop's bubblemon and wmfishtime together.
 *
 *
 * 0.4 2001/11/20
 *  - Added -t for time.
 *  - Changed a bit of the color of the clock's hands.
 *  - The code is still in a very "hacking" state. Not clean. Not good.
 *    Will be better :)
 *
 * 0.3 2001/07/16
 *  - Code tidying, fixes, etc.
 *
 * 0.2
 *  - Added -n for fishy network traffic
 *
 * 0.1
 *  - Got fish!
 *
 *
 * Pigeon (pigeon@pigeond.net)
 * http://pigeond.net/

/*  BubbleMon dockapp 1.32
 *
 *  - dockapp for Window Maker/Blackbox/E/Afterstep/SawBabble
 *  - Code outside of bubblemon_update copyright 2000, 2001
 *    timecop@japan.co.jp
 *  - oleg dashevskii <od@iclub.nsu.ru> made changes to collect memory
 *    and cpu information on FreeBSD.  Some major performance improvements
 *    and other cool hacks.  Useful ideas - memscreen, load screen, etc.
 *  - Adrian B <midnight@bigpond.net.au> came up with the idea of load
 *    meter.
 *  - tarzeau@space.ch sent in cute duck gfx and suggestions, plus some
 *    code and duck motion fixes.
 *  - Phil Lu <wplu13@netscape.net> Dan Price <dp@rampant.org> - Solaris/SunOS
 *    port
 *  - Everything else copyright one of the guys below
 *
 *  TODO: Anything else? Add fish?
