# Note the new usage of gs (Ghostscript) to optimize the PDF.  Obviously, one
# must have Ghostscript installed.  This optimization reduces the near 11 Mb
# PDF down to about 4 Mb in size, with no significant reduction in quality.
#
# However, lately it has started disabling the hyperlinks.  So using "optimize"
# or "opt" is no longer the default.
