CPU Watcher 0.5

CPU Watcher is a simple tool to monitor CPU usage,
free memory and network traffic.

It works by launching its own idling task (called "Uuno")
at priority -127. Task's execution time is measured and
the system load is determined, based on how much time
"Uuno" got during a time period (which is 1 second).


Features:

- shows the last 5 minutes of CPU usage (green graph)

- shows also the percentage of free
	* public memory (red graph)
	* virtual memory (blue graph)
	* video memory (light blue graph)

- shows also network traffic (activated with 'n' key)
	* upload speed (upper, red graph)
	* download speed (lower, green graph)
	* Current Kilobyte values are shown in Screen's titlebar
	The graphs show current/peak * 100% value.

- NEW: Supports now tooltypes which are hopefully self explained. Tooltypes
allow
storing the window position and setting the colours used in the window, too.


Keyboard commands:

	c - cpu graph ON/OFF.

	m - toggle between CPU measuring modes. Default mode uses busylooping,
	more accurate method (described above). Optional "Simple" mode
	doesn't busyloop, but it may not be as accurate.

	Screen's titlebar shows "B" for the busylooping method, and "S"
	for the simpler method.

	p - public memory graph ON/OFF.

	v - virtual memory graph ON/OFF.

	x - gfx/video memory graph ON/OFF.
	g - grid ON/OFF.
	s - solid drawing ON/OFF. No effect on network graphs.

	d - dragbar ON/OFF.

	n - network graphs ON/OFF.

	q - quit program.


Running both CPU Watcher and CPUClock.docky at the same time may not be
reliable.


ToDo list:

	- prefs editor for better configuration
	- tooltype support
