Am I being naive in suggesting that cpio be used?  While ar-archives are
not necessarily compatible between different machines (most obvious to me
when I tried to move an ar-archive from an AT&T 3b2 to a 3b1), ASCII cpio
archives seem to travel OK.  In addition, it would be fairly simple to
extract files from the archive, as follows:

#shell script to extract an ASCII cpio archive
cpio -icvd <<end_of_archive

[ASCII cpio archive]

end_of_archive
#end of shell script

While there is still the possibility of including some `nasty' commands,
it would be much easier to check for them since there should only be
ONE (or very few, at any rate) command executed in the script.

If I've overlooked some obvious problem, please break it to me gently -- I'm
a very sensitive person :-)...
