Unix zoo question

[lwv27 at CAS.BITNET]

I am trying to figure out what command parameters I would use if I
want to tell zoo to add files if they do not exist, update files if
the source is 'newer' (does that mean modification date?) AND delete
the files that it adds to the archive.

I tried zoo -uM file.zoo file1 file2 file3

but was told that was not a proper syntax.
