## 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.
