## Filename:    Makefile        (sw/dev)

##

## Project:     CMod S6 System on a Chip, ZipCPU demonstration project

##

## Purpose:     This makefile supports (directs) the building of the various

##              software for the S6 Cmod board.

##

##      Targets:

##

##      (all)           Builds all of the program files

##

##      clean           Removes all object files, the dependency file,

##                              and any programs that have been built.

##

##      depends         Builds a master dependency file
