Re: Patch to support dar_manager catalogues

Steven,

Nice job on the patch!  I have never used the dar_manager catalogues so I am glad you added this 
feature.  I plan on adding it to the next version of SaraB.

I have not tested the patch yet, but it looks good.  Thanks for your time and talent.

To everyone else, I apologize for not releasing in a while.  I have a new job that takes most of my 
free time, so SaraB has been left in the low-priority To-Do list.

During my last coding session, I was trying to implement Parchive, which would add redundancy to any 
archive.  This may help recover from physical corruption (such as a scratched DVD).  I also wanted 
to improve my install process, to a more standardized one.  (RPM)

For now, I think I will work on the small bugs that have been pointed out, and include Steven's 
patch.  Hope to get this release in the next month.

Tristan
