WD		 1This patches creates two new command line options as follows:
2 --delete-dir
3 --delete-suffix
4
5The delete-dir and delete-suffix options give the ability to store
6backup of deleted files on the receiver in different directories
7or with different suffix than the backup of files that have been
8changed but that are still on the source drive. Both commands can
9be combined.
10
11The default behaviour if one or both of the options are not specified
12is the previous behaviour, both backups use the same directory or
13suffix.
