you want to send several different directories at the same time. For
example, if you used the command
-verb(rsync foo/bar/foo.c remote:/tmp/)
+verb(rsync /foo/bar/foo.c remote:/tmp/)
then this would create a file called foo.c in /tmp/ on the remote
machine. If instead you used
-verb(rsync -R foo/bar/foo.c remote:/tmp/)
+verb(rsync -R /foo/bar/foo.c remote:/tmp/)
then a file called /tmp/foo/bar/foo.c would be created on the remote
-machine -- the full path name is preserved.

+That would create /tmp/bar/foo.c on the remote machine.
dit(bf(--no-relative)) Turn off the --relative option. This is only
needed if you want to use --files-from without its implied --relative
backup suffix used with the --backup (-b) option. The default suffix is a ~

dit(bf(--compare-dest=DIR)) This option instructs rsync to use em(DIR) on
-the destination machine as an additional directory to compare destination
-files against when doing transfers if the files are missing in the
-destination directory. Files that are identical to one of the specified
-directories are not transferred. This is useful for creating a sparse

+files against doing transfers (if the files are missing in the destination
+directory). If a file is found in em(DIR) that is identical to the
+sender's file, the file will NOT be transferred to the destination
+directory. This is useful for creating a sparse backup of just files that
+have changed from an earlier backup.
+
+Beginning in version 2.6.4, multiple --compare-dest directories may be
+provided and rsync will search the list in the order specified until it

dit(bf(--copy-dest=DIR)) This option behaves like bf(--compare-dest), but
rsync will also copy unchanged files found in em(DIR) to the destination
directory (using the data in the em(DIR) for an efficient copy). This is
useful for doing transfers to a new destination while leaving existing
files intact, and then doing a flash-cutover when all files have been
-successfully transferred. If em(DIR) is a relative path, it is relative to
