It turns out that for a package that should be able to be installed
without netbase being installed, should-* is the correct place to put
$network. But, if it requires netbase to be present to be able to work,
it should put $network in require-*. As most machines have netbase
installed anyway, it does not have much practical effect.
I'm going to keep them in the Required- fields and if that doesn't cut
the mustard, we can revisit the mustard plant.
ps - I'm planning on an upload soon, as I didn't received any
indications I should wait.
