-dit(bf(-x, --one-file-system)) This tells rsync not to cross filesystem
-boundaries when recursing. This is useful for transferring the
-contents of only one filesystem.
-
-dit(bf(--existing)) This tells rsync not to create any new files --
-only update files that already exist on the destination.
-
-dit(bf(--ignore-existing))
-This tells rsync not to update files that already exist on
-the destination.
-
-dit(bf(--max-delete=NUM)) This tells rsync not to delete more than NUM
-files or directories. This is useful when mirroring very large trees
-to prevent disasters.
-
-dit(bf(--max-size=SIZE)) This tells rsync to avoid transferring any
-file that is larger than the specified SIZE. The SIZE value can be
-suffixed with a letter to indicate a size multiplier (K, M, or G) and
-may be a fractional value (e.g. "bf(--max-size=1.5m)").
+dit(bf(-x, --one-file-system)) This tells rsync to avoid crossing a
+filesystem boundary when recursing. This does not limit the user's ability
+to specify items to copy from multiple filesystems, just rsync's recursion
+through the hierarchy of each directory that the user specified, and also
+the analogous recursion on the receiving side during deletion. Also keep
+in mind that rsync treats a "bind" mount to the same device as being on the
+same filesystem.
+
+If this option is repeated, rsync omits all mount-point directories from
+the copy. Otherwise, it includes an empty directory at each mount-point it
+encounters (using the attributes of the mounted directory because those of
+the underlying mount-point directory are inaccessible).
+
+If rsync has been told to collapse symlinks (via bf(--copy-links) or
+bf(--copy-unsafe-links)), a symlink to a directory on another device is
+treated as a mount point, while other referents are treated as though they
+existed on the device where the symlink is found.
+
+dit(bf(--existing, --ignore-non-existing)) This tells rsync to skip
+updating files that do not exist yet on the destination. If this option is
+combined with the bf(--ignore-existing) option, no files will be updated
+(which can be useful if all you want to do is to delete missing files).
+
+dit(bf(--ignore-existing)) This tells rsync to skip updating files that
+already exist on the destination. See also bf(--ignore-non-existing).
+
+dit(bf(--remove-sent-files)) This tells rsync to remove from the sending
+side the files and/or symlinks that are newly created or whose content is
+updated on the receiving side. Directories and devices are not removed,
+nor are files/symlinks whose attributes are merely changed.
