+intel-gen4asm is a program to compile an assembly language for the Intel 965
+Express Chipset.  It has been used to construct programs for textured video in
+the 2d driver.
 
 Some examples of gen4 assembly programs are in the doc/examples directory.
+
+Note that the language parsed by this assembler is not exactly what the final
+language is going to look like.  In particular, the send instructions need to
+be cleaned up and made more reasonable to program with.
