Hi Mike,

As Patrick suggested, 'rpm --help' will give you a quick snaphot/refresher of 
the most frequently used options. You might consider the procedure I use:

- copy the new rpms into an empty working directory and cd into it
- su + password to gain the appropriate permissions
- rpm -Uhv *.rpm --test

"U" will upgrade earlier versions (if they exist) or just install
"h" gives you hash mark progress bars with percentage completion
"v" is, of course, verbose mode (feedback)
"--test" does a 'dry run'. Nothing is actually written to disk and it advises 
you of any conflicts or missing dependencies. When you finally get the 'mix' 
right, drop the "--test" and install. And don't forget to run 'ldconfig' 
and 'SuSEconfig' afterwards.

hth & regards,

Carl
