I changed a couple of things:
a) Now there's a license notice (template from
/usr/src/share/misc/license.template). Nothing important, just to be
sure.
b) All packages which you didn't want to delete are saved to a file,
so you will not have to answer "n" in future runs (to check the full
list of packages just do: "sudo rm /etc/pkg_check.conf").
c) If, in a run, packages were deleted, a new run is suggested,
because maybe there are packages which were *only* used by those
packages.
Again, feedback is useful :)
