Help with info page generation

Hello -

   I'm starting with a docbook manual with the following (relevant) info 
section:

<book id="plplot-docbook">
   <bookinfo>
     <title>The PLplot Plotting Library</title>
     <titleabbrev role="texinfo-file">plplotdoc</titleabbrev>
     <abstract role="texinfo-node" xreflabel="PLplot">
       <para>The PLplot Plotting Library</para>
     </abstract>
     <subjectset scheme="texinfo-directory">
       <subject><subjectterm>Scientific 
Visualization</subjectterm></subject>
     </subjectset>

I end up with the following in my .texi:

INFO-DIR-SECTION Scientific Visualization
START-INFO-DIR-ENTRY
* The PLplot Plotting Library: (plplotdoc).   The PLplot Plotting Library
END-INFO-DIR-ENTRY

but I want:

INFO-DIR-SECTION Scientific Visualization
START-INFO-DIR-ENTRY
* PLplot: (plplotdoc).   The PLplot Plotting Library
END-INFO-DIR-ENTRY
