Each component is now broken up into multiple header + * files, corresponding to the sections above (e.g. instead of "foo.h", we now + * have "foo_types.h", "foo_structs.h", "foo_externs.h", "foo_inlines.h"). + * + * Those files which have been converted to explicitly include their + * inter-component dependencies are now in the initial HERMETIC HEADERS + * section.
