* fixes #2158 * handles version-specifiers (>,<,>=,<=,=) correctly * adds option "oldpackage", which is passed to zypper * this is implied as soon as a version is specified * it can be used independently to allow downgrades coming from repos * add __main__ check * extend documentation on version specifier
