DESCRIPTION

The glcells program draws cells that divide exponentially, eat and
eventually die.

OPTIONS

glcells accepts the following options:

--window
Draw on a newly-created window. This is the default.

--root Draw on the root window.

--window-id number
Draw on the specified window.

Food is ditributed randomly on the screen (Yes, the cells
need to eat). This parameter specifies the minimum amount of
food per pixel. Default is 5.

--maxfood num
Food is ditributed randomly on the screen (Yes, the cells
need to eat). This parameter specifies the maximum amount of
food per pixel. Default is 20.

--divideage num
Specifies the minimum age in frames a cell needs to have
before being able to divide. Default is 20

--mindist num
Specifies the minimum distance between cells. Default 1.4

--delay num
How long to pause between frames. Default is 20000, or 0.02
second.

--fps Display the current frame rate, CPU load, and polygon count.

--wireframe
Draw wireframe only.

--keepold
Dead cells stay on screen.
