Thanks for the tip, this looks like a very useful piece of documentation
to absorb.

(Fink's former leader, Christoph Pfisterer, knew a lot about both shared
 libs and dpkg; those of us who are left in the project are still trying to
figure everything out!)

It appears that dpkg's shlibs facility, as described in that document,
has not yet been made part of fink.  But it seems to be exactly what
we need, particularly since many fink packages are now building shared
libraries.

I think that the fink implementation could include a new fink tag "Shlibs"
which would name the shlibs file, and then fink would make the appropriate
calls to dpkg-shlibs to implement this.

I'll look into it further.
