rpmcompare.sh
This compares two similarly named rpms. This is good to make sure they are compatable.
To find out all the options, use the -h option
The most common options are -c and -r. These are used for the directories to compare.
Examples:
sh rpmcompare.sh -c /tmp/original/ -r /tmp/rebuilt/
The results will show up in the directory rpmcompareresults unless to change that option.
