New Revision: 51981
URL: https://svnweb.freebsd.org/changeset/doc/51981
Log:
Improve the introduction chapter, to fix the overall structure
of that part.
The diff is a bit large due to changed indentation, but it's mostly about
moving the <sect2> a bit further down and shortening the introduction part.
