# compile because it has no prerequisites and would be
# considered up-to-date all the time.
#
# NOTE: Rules only activate if the dependant files
# (right side of colon) have changed since the last time
# the make was run.
.PHONY: clean

# Ran independantly.
# Deletes all object files and the executable.
