[orca-list] updating Orca

[Glenn <glennervin cableone net>]

Hi All,
I have noticed that there have been a lot of things being worked out in 
Orca.
In the past, I have tried apt-get install orca
and apt-get never finds anything for orca.
Does Orca use a separate repository?
One would think that if a package came with an ISO, that we could get an 
update via apt-get.
Maybe there's something about this process that I'm not understanding.
What do all of you know about this?
Glenn
