# Unit test Makefile for spine/tests/unit
#
# The test binaries are self-contained: each one carries a copy of the routine
# under test so it links without MySQL, Net-SNMP or the spine globals.  Keep
# those copies byte-identical to the shipped source, or the tests stop being
# regression guards.
#
# Usage:
#   make          -- build and run
#   make build    -- build only
#   make clean    -- remove build artefacts
#
# test_linked exercises the full production object set and is intentionally
# driven by the top-level Automake suite, which supplies those dependencies.
