Nagios plugin for checking software updates
This plugin checks for software updates on systems that use package
management systems based on the zypper command found in openSUSE.
It checks for security, recommended and optional patches and also for
optional package updates.
You can define the status by patch category. Use a commata to list more
than one category to a state.
If you like to know the names of available patches and packages, use
the "-v" option.
