Problem Description: 

BugTraq ID #1069383 - 
	This is the patch for the AnswerBook not printing large "books"
	(chapters) on laserwriters or other postscript printers. The
	postscript generated has extraneous postscript between pages
	which has unbalanced gsave commands. This overflows the save
	stack limit of 31 for most postscript printers (not
	SparcPrinter however since XNeWS stack is much larger). The
	patch script filters out the offending postscript before it is
	passed to the printer.

BugTraq ID #1084755 -
	Some documents in AnswerBook made use of arguments to the
	PostScript setscreen function that Apple LaserWriters and some
	other printers would not accept.  The new "viewprint" script
	eliminates this problem.

Install Instructions: 

	Perform the following as user "root": 

	- If a previous version of this patch was installed, the
	  original "viewprint" file should be restored first, via:

            mv $ABHOME/.viewprint $ABHOME/viewprint

	- Move the original file to new name.  It will be used by
          the replacement "viewprint" file:

            mv $ABHOME/viewprint $ABHOME/viewprint.bin

	- Install the patch file:

            cp viewprint.sh $ABHOME/viewprint
