Duplicate body checksum...

In the man page at
http://www.rhyolite.com/anti-spam/dcc/dcc-tree/dccproc.html

the "-c type,hold" option is documented with 

    A common choice is -t CMN,25,50 to notice mail with common bodies
    or Received headers

Should this be "A common choice is -c ..."  (c, not t)? I don't
understand why you have what appears to be two thold's.

Am I right in thinking I can use "-c fuz1,MANY"? Can I use multiple
such tests, like

    ... | dccproc -w whiteclnt -c fuz1,MANY -c fuz2,MANY

Thanks.
