# Build the VERY BASIC reproduction pipeline dependencies (programs and
# libraries).
#
# ------------------------------------------------------------------------
# !!!!! IMPORTANT NOTES !!!!!
#
# This Makefile will be run by the initial `./configure' script. It is not
# included into the reproduction pipe after that.
#
# This Makefile builds very low-level and basic tools like GNU Bash and GNU
# Make. Therefore this is the only Makefile in the reproduction pipeline
# where you MUST NOT assume that modern GNU Bash or GNU Make are used.
#
# This Makefile is a very simplified version of `dependencies.mk' in the
# same directory. See there for more comments.
