+# 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 with gdb/binutils. Maybe we never will.
+# ship a Scheme interpreter (or other implementation) with gdb/binutils.
