svnserve SASL documentation?

Can someone who worked on adding SASL support to svnserve update
the man pages to explain how to use it? The comments in the
svnserve.conf in a new repository are less than helpful:

[sasl]
### This option specifies whether you want to use the Cyrus SASL
### library for authentication. The default is false.
# use-sasl = true
### These options specify the desired strength of the security layer
### that you want SASL to provide. 0 means no encryption, 1 means
### integrity-checking only, values larger than 1 are correlated
### to the effective key length for encryption (e.g. 128 means 128-bit
### encryption). The values below are the defaults.
# min-encryption = 0
# max-encryption = 256

The only answers i've heard so far were basically "sniff the
traffic" and "poke around your system package database for sasl
modules". This isn't acceptable.
