Our own Phil Hunter demonstrates the Owl River Company approach to the
remote host upgrade process with the RPM (i.e., the "RPM [and not the
inaccurately used 'Red Hat'] Package Manager"; this is Yet Another of those
'pun-nishingly' recursively named packages) and AutoRPM;
Also demonstrated were the alternative 'tarball' approach
[ tar zxf archive-version.tar.gz ; cd archive-version ;
./configure ; make ; sudo make install ], and the CPAN
perl archive install module method.
