* 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
