Another that developers can do is this:
sudo piuparts -d sarge -d etch -d sid -al foo.log foo
where foo is the name of their package. This needs a fairly fast access
to a mirror, however, but that can be somewhat avoided by creating a
chroot snapshot (see options -b and -s).
I'm running this on all packages in sid, and filing bugs about any
problems I find, but it does take time and it would be preferable that
package maintainers who can do it themselves do so.
Of course, what piuparts tests is not a complete test of all the
functionality of the package, only that the basics of installation,
upgrade, and removal work. Wait for version 2, please. :)
