dit(bf(--exclude=PATTERN)) This option allows you to selectively exclude
certain files from the list of files to be transferred. This is most
dit(bf(-0, --from0)) This tells rsync that the filenames it reads from a
file are terminated by a null ('\0') character, not a NL, CR, or CR+LF.
This affects --exclude-from, --include-from, and --files-from.
+It does not affect --cvs-exclude (since all names read from a .cvsignore
+file are split on whitespace).
dit(bf(-T, --temp-dir=DIR)) This option instructs rsync to use DIR as a
scratch directory when creating temporary copies of the files
linked.
Like bf(--compare-dest) if DIR is a relative path, it is relative
to the destination directory (which changes in a recursive transfer).
+An example:
+
+verb(

dit(bf(-z, --compress)) With this option, rsync compresses any data from
the files that it sends to the destination machine. This
The exclude and include patterns specified to rsync allow for flexible
selection of which files to transfer and which files to skip.

+Rsync builds an ordered list of include/exclude options as specified on
the command line. Rsync checks each file and directory
name against each exclude/include pattern in turn. The first matching
pattern is acted on. If it is an exclude pattern, then that file is
changing how much of the file tree is duplicated on the destination
system). The following examples demonstrate this.

The easiest way to see what name you should include/exclude is to just
look at the output when using --verbose and put a / in front of the name
(use the --dry-run option if you're not yet ready to copy any files).
