Rsync documentation is hard to understand

[CiderAndWhisky]

A working example for an rsync dir -> dir:

            "source": {
                "type": "rsync",
                "options": {
                    "path": "/some/source/dir",
                    "dirsync": "true"
                }
            },
            "target": {
                "dirname": "/backup/some/target/dir-%Y%m%d-%H%i",
                "filename": "ignored_by_rsync"
            },

Also, in the documentation the option is called "isDirSync", but really is "dirsync"
