The recent Posix release deprecates the cpio(1) utility, and replaces
it with the pax(1) utility. By default, pax writes the ustar format,
but with enhanced features taken from cpio. In addition, it fixes bugs
in both formats, e.g. by introducing the notion of character sets and
Unicode for file names in tar files.

As for accessing rpm: Redhat's rpm module does that, which is part of
the standard RPM distribution. Of course, it is a C extension, using
the RPM library.
