ps2pdf - Convert PostScript to PDF using ghostscript
   ps2pdf12   -   Convert   PostScript   to  PDF 1.2  (Acrobat 3-and-later
   compatible) using ghostscript
   ps2pdf13  -  Convert   PostScript   to   PDF 1.3   (Acrobat 4-and-later
   compatible) using ghostscript
   ps2pdf14   -   Convert   PostScript   to  PDF 1.4  (Acrobat 5-and-later
   compatible) using ghostscript


   ps2pdf  [options...] {input.[e]ps|-} [output.pdf|-]
   ps2pdf12  [options...] {input.[e]ps|-} [output.pdf|-]
   ps2pdf13  [options...] {input.[e]ps|-} [output.pdf|-]
   ps2pdf14  [options...] {input.[e]ps|-} [output.pdf|-]


   The ps2pdf scripts are work-alikes for  nearly  all  the  functionality
   (but  not  the  user  interface)  of  Adobe's Acrobat(TM) Distiller(TM)
   product: they convert PostScript  files  to  Portable  Document  Format
   (PDF) files.

   If the output filename is not specified, the output is placed in a file
   of the same name  with  a  '.pdf'  extension  in  the  current  working
   directory.  Either the input filename or the output filename can be '-'
   to request reading from stdin or writing to stdout, respectively,  when
   used as a filter.

   The three scripts differ as follows:

   -      ps2pdf12 will always produce PDF 1.2 output (Acrobat 3-and-later

   -      ps2pdf13 will always produce PDF 1.3 output (Acrobat 4-and-later

   -      ps2pdf14 will always produce PDF 1.4 output (Acrobat 5-and-later

   -      ps2pdf per se currently produces PDF 1.4 output.  However,  this
          may  change  in  the future. If you care about the compatibility
          level of the output, use ps2pdf12, ps2pdf13 or ps2pdf14, or  use
          the -dCompatibilityLevel=1.x switch in the command line.

   There  are  some  limitations  in  ps2pdf's  conversion.  See  the HTML
   documentation  for  more  information.  A   large   number   of   Adobe
   Distiller(TM)  parameters  which  can be used to control the conversion
   are also documented there, including instructions for generating  PDF/X
   and PDF/A documents.


   The ps2pdf scripts use the same options as gs(1).
