[Evolution-hackers] How to wirte a Contacts Python Plugin to call external program with arguments?

[Miguel Angel Cañedo <mcanedo grupogcm com>]

Hi:
I would like to write an evolution plugin (preferabily in python) to add
a very simple extension:

When looking at the contacts list in the addressbook, I want to add a
button, toolbar button, menu or contextual menu (what ever is easier),
that will call an external python progrm and will pass as arguments the
FullName and the Organization of the currently viewd contact.

I don't need the external program to return some kind of data back to
evolution.

Is this possible?

Can anyone point me to the right direction?

Thanks,
Miguel
