[orca-list] installing different versions of Orca

[Hermann <meinelisten onlinehome de>]

Hi,
as a consequence of my experience with the latest Orca, I plan to 
install different versions, a stable and a testing one.
So far no problem, but one question: How can I manage to store the 
personal settings of that two versions in different folders?
All personalized settings are stored in ~/.orca/user-settings.py and 
~/.orca/orca-customizations.py. 
So every setting I change in the stable Orca, also takes effect in the 
experimental branch and vice versa.
How to avoid this?
