   Mainly frees memory used by the document. Also closes a file, if it was not
   closed before with <function>ps_close</function>. You should in any case
   close the file with <function>ps_close</function> before, because
   <function>ps_close</function> not just closes the file but also outputs a
   last line containing the PostScript comment with the number of pages in the
   document. Without this comment, a PostScript viewer may not show the number
   of pages properly.
