[X-Unix] Panther "Archive" from command-line?

[Stephen Jonke]

After asking the question, the possible solution occurred to me - you  
can run BOMArchiveHelper from the command-line, although no useful man  
or help exists. I just tried running it with the file to zip as an  
argument and indeed that produces a .cpgz file that preserves resource  
forks. I.e.:

/./System/Library/CoreServices/BOMArchiveHelper.app/Contents/MacOS/ 
BOMArchiveHelper somefile_to_archive

However, from trial and error, it seems that this will only work if  
someone is logged into the computer (the GUI, that is) and you are that  
user (at the command line). You get an error about window server  
interaction if not, and sudo didn't seem to work around this. So...  
this still isn't the uber solution.
