[orca-list] how can i have two various versions of Orca installed

["Mgr. Janusz Chmiel" <ernesta tiscali cz>]

Dear developers,
I know, that using old mode for fetching ARIA live regions, lastly 
presentedin Orca 3.10 I thing can newer be e bring to The official Orca 
branch.
Unfortunately, not all WEB sites developers will be so kind or they are 
not allow to do proper ARIA markup because of their bosses. Or because 
this task is too complex to support proper ARIA live regions standards.
So can I have installed two various versions of Orca on The one Linux 
installation?


If yes, how to manage this?

I would had tovery probably compile older release Orca source code.
So this approach would replace my dream about two Orca modes related to 
Aria live regions fetching.

I have .deb package of last stable Orca version, which have supported 
old technique for fetching ARIA live regions.
My goal is The possibility to have orca 3.10 and newest Orca installed 
in Ubuntu Mate.
Thank You very much for Yours time and for Yours advice.

With kindness regards.
