[Xen-devel] [PATCH v3 2/2] Add a "make rpmball" target

[George Dunlap <george.dunlap@xxxxxxxxxxxxx>]

Build a simplistic dummy package, similar to "make debball", for
developers on rpm-based systems.

Signed-off-by: George Dunlap <george.dunlap@xxxxxxxxxxxxx>

v3:
 - Make more directories in temporary rpm area, so that rpmbuild
   from CentOS 5.x works
v2:
 - use --no-print-directory rather than '| grep -v :'
 - use find boot/ -type l -delete rather
 - bash-ify the script, so that we can...
 - use string manipulation to break down version and release numbers
 - Don't delete xen-syms, xen-*.gz links

+This package contains the Xen hypervisor and associated tools, built
+from a source tree.  It is not a fully packaged and supported Xen, just
+the output of a xen "make dist" wrapped in an .rpm to make it easy to
