## Filename:    Makefile
##
## Project:     XuLA2 board
##
## Purpose:     In case you don't want to fire up ISE, this Makefile attempts
##              to coordinate the build process without it.  While it works in
##      testing, there are some problems to this approach.  The first is that
##      if you bust timing, you may never know it--nothing will tell you it
##      failed.  Second, the output file is different from the output file
##      produced via ISE.  Still ... for a command line make script, it is a 
##      (good) start.
##
##      Makefile targets:
##
##      xula.bit        The FPGA bitfile or configuration file
##
##      objdir          Makes a directory for temporary build files, which can
##                      then be removed later with a clean target.  While a 
##                      great idea in principle, this doesn't work well in 
##                      practice since Xilinx's ISE never uses it.
##
##      clean           Removes intermediate build files.
