which file for Orca

[MICHAEL WEAVER <michaelweaver1 btinternet com>]

Which file should I download for the latest version of Orca if the one  
packaged
for Ubuntu in Universe is out of date or doesn't it matter as  to which 
format type
is used?
Do I need the one with the .ta extention or the .bz2 extention?
I might be able to burn the two zipped files to CD but I don't know if  
both would
try to be uncompressed at the same time and cause a problem  if I put 
the CD in my
laptop which is why I ask which file extention?
I would be doing it this way because I am getting help to install Orca  
from someone
at a couple of LUGs I attend.
