Excellent, thanks!

Maemo-optify can be invoked in a number of ways.  I'll explain what
happens when the modified dpkg-buildpackage calls 

    maemo-optify-deb --auto

after running ./debian/rules build.

Nothing will be done because debian/optify does not exist, and the
default mode is "none".

Nothing will be done because debian/optify does not exist, and the
default mode is "none".

If debian/optify exists with the contents "auto", then the binary package
will be optified with the default heuristic.

The default heuristic will not do anything because it detects that the
binary package already contains a file or directory called "/opt" and it
will explicitly stop because of that.

If debian/optify exists with the contents "auto", then the two packages
will be optified separately with the default heuristic.

The default heuristic will not do anything for the package that contains
"/opt", as described above.

For the package that does not contain "/opt", the default heuristic will
move ((files and (directories that have the same name as the package))
and are bigger than 2048 bytes) into /opt/maemo/.
