=item * Description: 

 PS files from plottree - multiple pages fail to display
 unless 'Respect DSC' is unchecked.

 From all reports, it seems as if the PS files conform to postscript;
 the program gs displays them without error. However, the program 'gv'
 fails to display anything other than the first page. In order to see
 the other pages, you either have to click 'Redisplay' (which I imagine
 is not designed to view other pages) or disengage the 'Respect DSC' option.

 DSC requires that each page be distinctly separate from the other, as
 far as the code is concerned. However, the way the BigPrint code works is to
 reproduce the entire graph on a sheet of paper, then clip off appropriately.
 This is repeated for each sheet, so I am unsure whether this method is DSC-
 appropriate.

 I should also note that PDF files are generated just fine and contain
 multiple pages that are recognized by all PDF viewers.

=head2 ID: 0004 Margin loss in PDF conversion of multi-page nexplot-generated Postscript

=item * Description 

 PDFs do not have margins, PS files do (plottree.pl)

 The BigPrint code apparently leaves margins (1/2" at this point in time) all
 around, so that one can print them without having things cut off. However,
 when converting to PDF, this doesn't happen. Instead, the margins only apply
 to the first page and don't apply to everything else. I don't know why this
 happens, but I'm guessing the fault isn't totally on our side. This should
 be looked into more deeply.

=item Description 

 plottree.pl (now nexplot.pl) - psresize does not work with any
 plottree-generated PS files. Any time we psresize a plottre-generated PS file, we get
 a blank page. We need to fix this. This is probably because in some way,
 the file doesn't follow DSC rules (see bug 0003 for details).

=item * Description

 Weigang noticed 3 weeks ago that plottree's internal node names are 
 not the same as the ones in SPAN.  They often look the same because 
 they are generated by a similar algorithm.  However, we need to 
 implement and test the correct transmission of internal node names 
 via the TREES block.
