Mesa is distributed in several parts:
MesaLib-x.y.z - the main Mesa library source code, drivers
    and documentation.
MesaDemos-x.y.z - OpenGL demonstration and test programs.
    Most of the programs require GLUT (either the
    
http://www.opengl.org/resources/libraries/glut.htmloriginal GLUT by Mark Kilgard  or
    
http://freeglut.sourceforge.netfreeglut  or
    
http://freeglut.sourceforge.netOpenGLUT ).
MesaGLUT-x.y.z - Mark Kilgard's GLUT, easily compiled and used
    with Mesa.  Plus, other implementation of GLUT for DOS, OS/2, BeOS, etc.
If you're not interested in running the demos, you'll only need the first
package.
The packages are available in .tar.gz, .tar.bz2 and .zip formats.
Other organizations might offer additional package formats.
Unpacking
All the packages should be in the same directory prior to unpacking.
To unpack .tar.gz files:
	tar zxf MesaLib-X.Y.tar.gz
	tar zxf MesaDemos-X.Y.tar.gz
	tar zxf MesaGLUT-X.Y.tar.gz
or
	gzcat MesaLib-X.Y.tar.gz | tar xf -
	gzcat MesaDemos-X.Y.tar.gz | tar xf -
	gzcat MesaGLUT-X.Y.tar.gz | tar xf -
or
	gunzip MesaLib-X.Y.tar.gz ; tar xf MesaLib-X.Y.tar
	gunzip MesaDemos-X.Y.tar.gz ; tar xf MesaDemos-X.Y.tar
	gunzip MesaGLUT-X.Y.tar.gz ; tar xf MesaGLUT-X.Y.tar
To unpack .tar.bz2 files:
	bunzip2 -c MesaLib-X.Y.tar.gz | tar xf -
	bunzip2 -c MesaDemos-X.Y.tar.gz | tar xf -
	bunzip2 -c MesaGLUT-X.Y.tar.gz | tar xf -
To unpack .zip files:
	unzip MesaLib-X.Y.zip
	unzip MesaDemos-X.Y.zip
	unzip MesaGLUT-X.Y.zip
