#
# This Makefile has been completely re-vamped. Two reasons, first to allow
# for a full compile before installation, hence allowing us to make a binary
# distribution without installing and second to allow proper dependancy trees
# for the different versions of the library.
#
# As an aside, it would be useful if I could avoid GNU-make constucts.
