 #
 # ACTION is currently always "opcodes". It exists to be consistent with the

 # 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

 # 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.
