From the http://kernel.org/doc/Documentation/kbuild/kconfig-language.txt
- help text: "help" or "---help---" This defines a help text. The end of the help text is determined by the indentation level, this means it ends at the first line which has a smaller indentation than the first line of the help text. "---help---" and "help" do not differ in behaviour, "---help---" is used to help visually separate configuration logic from help within the file as an aid to developers.
