# Descr:  Makefile to create application Makefiles from a template.

# Abandon all hope ye who look in here.
# This Makefile builds all the application Makefiles
# using template Makefiles and a python script makemake.py that parses
# the applications looking for #includes.
# It also creates the doc directories and the callgraphs, etc.
