# 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 (the GNU implementation of)
# various Unix commands, and therefore probably won't work in a Windows
# environment (besides maybe cygwin).  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)
