+# WARNING: this file locates files differently from the other pbuilder
+# functions:
+# - if PBUILDER_CHECKOUT is set, it is assumed that testlib.sh is sourced from
+#   a pbuilder checkout (e.g. from the upstream Makefile or Debian build)
+# - otherwise, PBUILDER_TEST_ROOT or PBUILDER_TEST_*DIR should be used to
+#   locate files instead of PBUILDER_ROOT and PBUILDER_*DIR since
+#   testlib_setup_env() overrides these vars to run the other pbuilder modules
+#   with a fake environment
+
+# if this is set, use pbuilder files from this location; otherwise, use
+# installed files (from PBUILDER_TEST_ROOT, which is a copy of PBUILDER_ROOT)
