Mesa 3D graphics library modules [XFree86]
 Chipset-specific DRI modules for the Mesa library, if available for your
 machine architecture, are provided in this package. (Unlike the modules in
 the xserver-xfree86 package, the DRI modules are loaded by the Mesa library,
 not by the X server itself.)
 .
 This package suggests the libglide3 package, which is necessary for 3D
 acceleration support for users of 3Dfx Interactive's Voodoo Banshee, Voodoo3,
 Voodoo4, and Voodoo5 cards. Users of other video cards need not install
 libglide3. Note that 3D acceleration support for 3Dfx cards is not available
 for the PowerPC and SPARC architectures.
