This is useful if the files are compressed at the source.  If you want
only the destination side to be compressed, you'll need something beyond
a stock rsync.  One option that I'm aware of is the BackupPC program
which is referenced on the "resources" page of rsync's website.

The patch is in the "patches" dir of the rsync distribution under the
name gzip-rsyncable-checksum.diff.
