# The code below generates a separate .mk file for each target, but
# all are sourced by the top-level Makefile. This means that all

# where appropriate for immediate evaluation, and similarly to watch
# that you're not relying on a variable value to last beween different
# .mk files.
#
# TODOs:
#
# Global settings and utility functions are currently stuffed in the
# toplevel Makefile. It may make sense to generate some .mk files on
# the side to keep the the files readable.
