Bug#466456: How to list

[Rolf Leggewie]

To Steve or anybody who is also looking for a simple way to list all
installed packages derived from $sourcepackage:

grep-status -FSource $sourcepackage

Of course, it would be nice if wnpp-alerts "grew" a switch to display
this information directly.  It should be easy enough to do with
dpkg-ctrl (use of dpkg-status is discouraged in scripts).
