This option also handles ACLs (if bf(--acls) was specified) and non-user
extended attributes (if bf(--xattrs) was specified).

Since there is only one "side" in a local copy, this option affects both

"localhost" if you need to avoid this, possibly using the "lsh" shell
script (from the support directory) as a substitute for an actual remote
shell (see bf(--rsh)).
filesystem. It doesn't seem to handle seeks over null regions
correctly and ends up corrupting the files.
-dit(bf(-n, --dry-run)) This tells rsync to not do any file transfers,
-instead it will just report the actions it would have taken.
+dit(bf(-n, --dry-run)) This makes rsync perform a trial run that doesn't
+make any changes (and produces mostly the same output as a real run). It
+is most commonly used in combination with the bf(-v, --verbose) and/or
+bf(-i, --itemize-changes) options to see what an rsync command is going
+to do before one actually runs it.
+
+The output of bf(--itemize-changes) is supposed to be exactly the same on a
+dry run and a subsequent real run (barring intentional trickery and system
+call failures); if it isn't, that's a bug. Other output is the same to the
+extent practical, but may differ in some areas. Notably, a dry run does not
+send the actual data for file transfers, so bf(--progress) has no effect,
+the "bytes sent", "bytes received", "literal data", and "matched data"
+statistics are too small, and the "speedup" value is equivalent to a run
+where no file transfers are needed.
dit(bf(-W, --whole-file)) With this option the delta transfer algorithm
is not used and the whole file is sent as-is instead. The transfer may be
