$0 [--help | --add=/full/path/to/file --remove=/full/path/to/otherfile --file=/path/to/cpanelsync_exclude_file (optional) ]

You can specify zero or more of either --add or --remove

Files are removed first then files are added. Files are added in the order specified.

The "--file" option allows you to edit a specific cpanelsync.exclude file rather than the global one.
