Usage: [ --include-pyc ] [ --include-cfg ] --skip-multi [ pkg ... ]
This utility scans the installed RPMs to compare checksums of files.
By default, files flagged as config are skipped, as are python pyc files.
Optional arguments:
--include-pyc : Include pyc files in check
--include-cfg : Include config files in check
--skip-links : Skip symlink check
--skip-multi : Skip the search for files with multiple owners
pkg : Specify one or more packages to limit the scan
(implies --skip-multi)
