pax 1:20090728-1build1 (sparc binary) in ubuntu lucid

 Pax is an archiving utility that reads and writes tar and cpio formats,
 both the traditional ones and the extended formats specified in IEEE 1003.1.
 It handles multi-volume archives and automatically determines the format
 of an archive while reading it. The pax interface was designed by IEEE
 1003.2 as a compromise in the chronic controversy over which of tar or
 cpio is best.

 This is the free OpenBSD's version written by Keith Muller.
