packaging unoconv

Hello,

I'd like to package unoconv on GuixSD

I discussed this previously on the users mailing list
https://listarchives.libreoffice.org/global/users/msg201500.html

GuixSD has Libreoffice 5.1.6.2

The GuixSD policy is to unbundle and disentangle when possible.
So I'd be happy to make unoconv work with the system provided python

Around the internet many pages suggest to use the Python interpreter
supplied by the Libreoffice suite and use that interpeter prompt to load
the UNO based libraries.

Is this suggestion still valid ?

In the path

...lib/libreoffice/program

I see no python interpeter to call

instead, I see a libpyuno.so and a pyuno.so, among many others

What are those and how do I use them ?

Thanks in advance
