This was not a title, but an example, as I used +adding-packages-generic.txt+
for inspiration. I thought it was useful to have the code snippets listed in
the example section, so the user could quickly jump to them. But it is true
that:

1. not all the code snippets are listed as examples.
2. the Ascidoc example syntax, mixed with a code snippet, hurts the eyes
   (either in text or in the generated HTML).

I'll change to plain and simple titles.
