[sugar] How to start a binary executable through an activity?

[Teus Benschop]

Good evening,

Any help on the following problem, probably simple for you, will be 
appreciated.

I seem to be unable to find information on how to start a binary from an 
activity.
There is the Myactivity.activity directory, and that may contain the 
activity.py file that contains the bulk of the work to be done.
I would be glad to hear how this activity.py could start binary 
/usr/bin/mybinary
This binary is supposed to start as soon as the activity icon is clicked.

Thank you,

Teus Benschop
