switching between stable, testing and devel

[Marco Martin]

Hi all,
in the last published repos (not in released images yet)
we have a nice addition, a small commandline application,  "ssu":

it makes easy to switch back and forth between a released image, testing and 
devel.

so, for instance if you have  the future released pa4 or an image built from 
testing, and you want to switch to bleeding edge devel, you can just do(as 
root):

ssu fl devel
zypper refresh
zypper dup

where ssu fl means "flavor" that can be chosen between "stable", "testing" and 
"devel"

Cheers,
Marco Martin
