+# 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 \
+#         arch-file opc-file options [extrafiles]
+#
+# ACTION is currently always "opcodes". It exists to be consistent with the 
+# simulator.
+# ARCH is the name of the architecture.
+# It is substituted into @arch@ and @ARCH@ in the generated files.
+# PREFIX is both the generated file prefix and is substituted into
+# @prefix@ in the generated files.
+# ARCH-FILE is the name of the .cpu file (including path).
+# OPC-FILE is the name of the .opc file (including path).
+# OPTIONS is comma separated list of options (???).
+# EXTRAFILES is a space separated list (1 arg still) of extra files to build:
+#	- 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.
