rsync - Sep 2010 - what is the default value for --compress-level=?

What is the default value for --compress-level=? 6? 9?

The fine manual only mentions:

       --compress-level=NUM
              Explicitly set the compression level to use (see --compress)
instead of letting it default.  If NUM is non-zero, the --compress option is
implied.


Also, what are allowed values? 1-9? 0-9? Something else?

Rsync tells the zlib library to "use the default compression", so if
we read
zlib's docs, it says this:

   Z_DEFAULT_COMPRESSION requests a default compromise between speed and
   compression (currently equivalent to level 6).

Rsync's docs should probably mention that too.
