# Source function library and configuration
# being run. The idea is that when the configuration changes, "service
# plc restart" is called, all dependencies are fixed up, and
# everything just works.
+
+### NOTE.
+# we want the resulting myplc to be able to easily skip
+# some steps. e.g. the packages step takes ages if you install
+# all rpms under the repository.
+# We skip steps whose name contains a dot (.) or a tilde (~)
+# this way the operations would just rename a step name e.g.
+# cd /etc/plc.d
+# mv packages packages.hide
+#
+# The drawback is, this stuff does not survive an rpm update
+# but that's maybe a good thing, that all is done at first start
+###
