 7.2.1 Invoking 'grotty'
 -----------------------
 
 The postprocessor 'grotty' accepts the following command-line options:
 
 '-b'
      Do not overstrike bold glyphs.  Ignored if '-c' isn't used.
 
 '-B'
      Do not underline bold-italic glyphs.  Ignored if '-c' isn't used.
 
 '-c'
      Use overprint and disable colours for printing on legacy Teletype
      printers (see below).
 
 '-d'
      Do not render lines (this is, ignore all '\D' escapes).
 
 '-f'
      Use form feed control characters in the output.
 
 '-FDIR'
      Put the directory 'DIR/devNAME' in front of the search path for the
      font and device description files, given the target device NAME.
 
 '-h'
      Use horizontal tabs for sequences of 8 space characters.
 
 '-i'
      Request italic glyphs from the terminal.  Ignored if '-c' is
      active.
 
 '-o'
      Do not overstrike.
 
 '-r'
      Highlight italic glyphs.  Ignored if '-c' is active.
 
 '-u'
      Do not underline italic glyphs.  Ignored if '-c' isn't used.
 
 '-U'
      Do not overstrike bold-italic glyphs.  Ignored if '-c' isn't used.
 
 '-v'
      Print the version number.
 
    The '-c' mode for TTY output devices means that underlining is done
 by emitting sequences of '_' and '^H' (the backspace character) before
 the actual character.  Literally, this is printing an underline
 character, then moving the caret back one character position, and
 printing the actual character at the same position as the underline
 character (similar to a typewriter).  Usually, a modern terminal can't
 interpret this (and the original Teletype machines for which this
 sequence was appropriate are no longer in use).  You need a pager
 program like 'less' that translates this into ISO 6429 SGR sequences to
 control terminals.
