Grouping messages by author

[Cyrus Vesuna]

Hi,
I'm trying to format my list so that it looks like this

http://sources.redhat.com/ml/c++-embedded/1998/authors.html

i.e
   Author0
       Mesg1
       Mesg2
       Mesg3
   Author1
       Mesg1
       Mesg2

I created the follow mrc file (which is incorrect)

<AUTHSORT>
<LiTemplate>
 <H3>$FROMNAME$</H3>
        &nbsp&nbsp&nbsp&nbsp $SUBJECT$
</LiTemplate>

it appears as
     Author1
            Mesg1
     Author1
            Mesg2

Which directives do I look at to create such groupings?


Invoked as
mhonarc $MAIL -rcfile ~/myresource.mrc -idxfname "byauth.html"

Versions:
  MHonArc v2.6.15 (Perl 5.008003 linux)
  Linux lserve 2.6.10-1.771_FC2

Thanks
Cyrus
