I absolutely agree that collapse code structures and code structure movements
improves coding practice.  Then with headings you can categorise various sections
of the file that could also be independently manipulated.

At this point, it would first be beneficial to handle the specification of
outline-heading-alist that users could successfully adapt te their needs.

Currently I want to handle texinfo files first because there is already
outline-heading-alist being defined in "texinfo.el".  Then look at elisp.
