//
//	This program illustrates the g2 graphics
//	library by opening a window and drawing
//	a face.
//
//	Compile it with:
//
//	g++ -o face face.cpp -L/usr/X11R6/lib -lm -lX11 -lgd -lg2
//
//	To get the hang of programming with
//	graphics, try changing colors on the
//	face, or drawing a different mouth,
//	or adding hair.
