set-based package filtering #4

This looks like a cool tool (I saw it referenced on IRC).

I think it could be more useful if the dependencies of both metapackages were collected. Then, a single apt line could be written to install needed packages, remove unneeded packages, and leave alone the packages that are needed in both metapackages.

This way, it wouldn't remove packages that would then be reinstalled seconds later.

Once it leaves alone packages that will don't change, it could be switched to an apt-get purge command instead. (purge can install packages, too, if you suffix them with a +.)

For example:

$ sudo apt-get purge libgweather-common pdns-tools+

The following packages will be REMOVED:

Using purge would clean up old configs, too.
