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:

- mark document title;
- use :Author: and :Date: for authorship;
- adjust notation for literals and bold;
- mark literal blocks;
- adjust identation.
