+Kbuild/Config.in/usage/applets.h snippets in .c files
+-----------------------------------------------------
+
+The old way of adding new applets was to put all the information needed by the
+configuration and build system into appropriate files (namely: Kbuild.src and
+Config.src in new applet's directory) and to add the applet declaration and
+usage info text to include/applets.src.h and include/usage.src.h respectively.
+
+Since the scripts/gen_build_files.sh script had been introduced, the preferred
+way is to have all these declarations contained within the applet .c files.
+
+Every line intended to be processed by gen_build_files.sh should start as a
+comment without any preceding whitespaces and be followed by an appropriate
+keyword - kbuild, config, usage or applet - and a colon, just like shown in the
+first example above.
