- # Included makefile for creating a kernel module.
- # Variables provided by Makefile that includes this one:
- # NAME module name
- # SRCS all sources for the module for the current target
- # machine
- # ALLSRCS all sources for the module, including all sources
- # for all target machines (used for ctags)
- # OBJS object files from which to create the module
- # CLEANOBJS object files to be removed as part of "make clean"
- # (need not just be object files)
- # HDRS all header files for the module
- # TM target machine type for object files etc.
- # MACHINES list of all target machines currently available
- # for this program.
