+=head2 Debugging
+
+The debugging of this module is pretty difficult, because we have

+In interactive mode you can try "o debug" which will list options for

+worth to give it a try and send me more specific output. You should
+know that "o debug" has built-in completion support.
+
+=head2 Floppy, Zip, and all that Jazz
+
+CPAN.pm works nicely without network too. If you maintain machines
+that are not networked at all, you should consider working with file:
+URLs. Of course, you have to collect your modules somewhere first. So
+you might use CPAN.pm to put together all you need on a networked
+machine. Then copy the $CPAN::Config->{keep_source_where} (but not
+$CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
+of a personal CPAN. CPAN.pm on the non-networked machines works nicely
+with this floppy.

+we should give coverage for _all_ of the CPAN and not just the
+__PAUSE__ part, right? In this discussion CPAN and PAUSE have become
+equal -- but they are not. PAUSE is authors/ and modules/. CPAN is
+PAUSE plus the clpa/, doc/, misc/, ports/, src/, scripts/.
-=back
+Future development should be directed towards a better intergration of
+the other parts.
