# title: Compare-DellUpdates
# description: This script will compare the bios/firmware/driver/OMSA versions of a remote server against the Dell SUU update package. To use it, get a copy of the latest Dell SUU. Inside the SUU file structure, look for catalog.xml in the repository. This file will be read to determine the latest versions, and compare it to the currently installed versions on the remote machine (reporting any differences). The output can be used to easily push updates as well, since the update file name is returned in the results.
