I was surprised just now to notice that Dirvish (www.dirvish.org) isn't mentioned on the Resources page. It should probably be mentioned in the same place that BackupPC is mentioned; they do similar jobs, though in different ways. This is a particularly startling omission since jw schultz, the original author of Dirvish, was also a frequent contributor to the rsync codebase. Thanks.
I hadn't noticed its absence before (especially since jw never added it himself or asked for it to be added). It's there now.
