That would work, but it seems to me that it should be possible to have
each 'pd' package independent, which I think is desireable. I think
that putting the docs and 'extra' stuff into each package's /usr/lib/
(puredata, pdextended, desiredata) will work the best with the fewest
disadvantages. Then libraries will have their help patches with them
wherever they are installed.

So how then to have shared library packages?

This sounds like a bad option to me, I think the problems of getting
them working together are not very hard, we just need to agree on the
