# makefile for the ergoDOX project
#
# This should produce a single file (probably in an archive format) for
# distribution, containing everything people will need to use the software.
#
# DEPENDENCIES:  This is unabashedly dependant on various Unix commands, and
# therefore probably won't work in a Windows environment.  I'm sorry...  I
# don't know a good portable way to write it.
#
# TODO:
# - include doc files (and maybe render them in html)
# - include the UI stuff (once it's done)
