-ocp-indent will look for `~/.ocp/ocp-indent.conf` to setup its default, then
-search for a `.ocp-indent` file in the current directory and its parents,

+If a `.ocp-indent` file is found in the current directory or its ancestors, it
+overrides definitions from `~/.ocp/ocp-indent.conf` and the built-in default.
+The command-line can of course still be used to override parameters defined in
