I think it's time to think about how this feature should be implemented.
Christophe already provided a wrapper script missing the parts where he
needed to wait for me.  He could finish it now if requested.

Do you, popcon maintainers, prefer to add such a wrapper (not a fork as
originally planned by Christophe) around orphaner to your package or
should I try to merge his work into orphaner?  As already said, I'd be
happy with both.

The required changes in deborphan, adding the option --include, have
just been made and will be part of the next release.  I forgot that
there is already an option --guess-only, which (now, after a litte
adaption) does the same as --no-libs would have done:

    $ ./deborphan --guess-only -i wml,apt,acl,wiggle,perl
    wml
    wiggle
    acl

The wrapper needs to to something like tr '\n' ',' to get the list
format needed by deborphan, for example (not tested):

    orphaner --show-size --guess-only -i $(popcon-largest-unused \
                                         | awk '{print $2}' \
                                         | tr '\n' ',' \
                                         | sed 's/,$//')

To be able to test your wrapper you need either to build the debian
package and install it, or add something like this to orphaner.sh:

    alias deborphan="/path/to/your/workingcopy/trunk/src/deborphan"

You need to run the following commands to install the build dependencies
and to create the required makefiles to build deborphan:

    As root:
        apt-get install build-essential subversion
        apt-get build-dep deborphan

    To get the code run as user:

        svn co svn://svn.debian.org/deborphan/trunk

    And to generate the makefiles:
        cd trunk
        ./autogen.sh
        ./configure
