+// Purpose:    This program generates the zip-ops.md machine description file.
 
+//
 
+//     While I understand that this is not GCC's preferred method of generating
 
+//     machine description files, there were just so many instructions to
 
+//     generate, and so many forms of them, and the GCC infrastructure didn't
 
+//     support the conditional execution model of the ZipCPU that ... I built
 
+//     it this way.
 
+//
 
+//     As of this writing, building zip-ops.md is not an automatic part of
 
+//     making GCC.  To build genzipops, just type:
 
+//
 
+//     g++ genzipops.c -o genzipops
 
+//
 
+//     And to run it, type:
 
+//
 
+//     genzipops > zip-ops.md
 
+//
 
+//     genzipops takes no arguments, and does nothing but write the machine
 
+//     descriptions to the standard output.
