   That's cool. Can the form of "archive.xml" be extended to act as a a
manifest? I presume that would require an extension to the OpenSim modules
that handles compressing content to tar.gz files. It would have to
extensively parse, then list all items of content in some kind of tree
format and write this as "archive.xml" before calling tar. My best guess any
way.



I also think that the issue of sharing content is seperate from the

This I knew and I'm making use of the fact that OAR/IAR can be decompressed
into a folder tree outside of OpenSim. However it would be helpful to be
able to view the contents of an OAR from within the OpenSim command line
environment, rather than having to switch back and forth between a terminal
running OpenSim and a terminal running the native os shell. Basically the
ability to call tar, ls, mkdir and rm functions from within OpenSim would
probably satisfy this need (a module supporting native shell commands?).

Thanks for your helpful comments and redirects, Justin.
