#  Script for converting the CGAL manuals to PDF with bookmarks. 
#  Have to do a separate run of latex to generate this because otherwise
#  the things that are linked via the hyperref package are colored in the
#  PostScript manual as well.
#
#  N.B.  gs version 6.51 works best for the basic library conversion.
#        version 6.50 gives up or segmentation faults or does other nasty
#        things.
