I second that but am not looking for *exactly* what Sebastian is
interested in.

I'd be fairly happy if, at the end of the delete run (be it single
or multiple packages), I could easily extract all the commands,
i.e. rm, (group|user) del, etc. without having to copy paste it
anywhere and use sed or awk (dangerous!).

To sum it up is there a way, and if not, would there be an interest
to add one, where package deletion can create a shell script template,
which one can then edit, if need be, and/or run it simply with, i.e.:

sh ./pkg_delete_cleanup_template

Using Sebastian's example above, the content of said file could
look something like this:

rm -rf /etc/cups/*.conf.O /var/log/cups
rm /etc/cups/cupsd.conf # (which was modified)
rm /etc/cups/classes.conf # (which was modified)
rm /etc/cups/printers.conf # (which was modified)
rm /etc/cups/subscriptions.conf # (which was modified)
rm /etc/cups/snmp.conf # (which was modified)
rm -rf /var/cache/cups
rm -rf /var/spool/cups

Comments (and their indentation) are optional but might be useful to
some.
