+# Generate CGEN opcode files: arch-desc.[ch], arch-opc.[ch],
+# arch-asm.c, arch-dis.c, arch-opinst.c, arch-ibld.[ch].
+#
+# Usage:
+# cgen.sh action srcdir cgen cgendir cgenflags arch prefix options
+#
+# ACTION is currently always "opcodes". It exists to be consistent with the 
+# simulator.
+# OPTIONS is comma separated list of options:
+#	- opinst - arch-opinst.c is being made, causes semantic analysis
+#
+# We store the generated files in the source directory until we decide to
+# ship a Scheme interpreter (or other implementation) with gdb/binutils.
+# Maybe we never will.
+
+# We want to behave like make, any error forces us to stop.
