Various dependencies that can be satisfied by multiple packages are shown.
</p><p>
<tt>aptitude-doc</tt> is a virtual package that is provided by various
(unspecified) other packages.
</p><p>
<tt>libxml-simple-perl</tt> has a dependencies with one alternatives that
has a special indicator.
The square brackets ("[...]") for <tt>libxml-sax-expat-perl</tt> indicates
that that package is also shown separately elsewhere in the graph (and its
dependencies will be shown from that separate instance).
Braces ("{...}") are used to indicate that the dependencies of an alternative
are not shown in the graph.
