Each text file under Documentation follows a different format. Some doesn't even have titles! Change its representation to follow the adopted standard, using ReST markups for it to be parseable by Sphinx: - promote main title; - use the right markup for footnotes; - use bold markup for files name; - identify literal blocks; - add blank lines to avoid Sphinx to complain; - remove numeration from titles.
