   5 # Wrapper for GNU groff to convert man pages to a few formats
   6 #
   7 # Usage: manconv.sh FORMAT [PAPER_SIZE] < in.1 > out.suffix
   8 #
   9 # FORMAT can be ascii, utf8, ps, or pdf. PAPER_SIZE can be anything that
  10 # groff accepts, e.g. a4 or letter. See groff_font(5). PAPER_SIZE defaults
  11 # to a4 and is used only when FORMAT is ps (PostScript) or pdf.
  12 #
  13 # Multiple man pages can be given at once e.g. to create a single PDF file
  14 # with continuous page numbering.
