Just to add an extra 5c, don't forget the news groups can have
additional useful information:

Instead of asking for an open sourcing of the tool, what is the
high-level thing you want to do?
Based on your questions, it sounds like you want to know how pax
supports resource forks
and finder info in Tiger, and emulate that. If this is the case,
you probably want
to look look at the implementation of copyfile_pack() in Libc:
<http://darwinsource.opendarwin.org/10.4.2/Libc-391/darwin/
copyfile.c>
This has all of the "Support extended attributes, including
resource forks
and finder info" functionality as advertised for Tiger, and is
used by gnutar, pax, etc.
Actually that's not the purpose. I'm trying:
- to find a solution to be able to split forks correctly (for
folders) on 10.2. This may require writing my own tool (therefore
the quest some kind of documentation which allows me to fully
understand the AppleDouble format and the request for open sourcing
SplitForks)
- to understand why some folder (FolderInfo struct) flags are not
restored by Installer.app when not using PackageMaker.
- to extract a ._ resource fork file from a .pax.gz file so that I
can have a look at its data. I tried using Pacifist which is a
great tool but it does not allow me to extract just a ._ file (when
it's at the root of the hierarchy).
I'm happy to be told that pax is open sourced. I must confess that
when I posted I was at the end of a try and debug queue where I
found more problems than solutions and so forgot to google for pax
(which I did for AppleDouble). Mea culpa, mea maxima culpa.
