groff: Invoking grops
7.3.1 Invoking 'grops'
----------------------
The postprocessor 'grops' accepts the following command-line options:
'-bFLAGS'
Use backward compatibility settings given by FLAGS as documented in
the 'grops(1)' manual page. Overrides the command 'broken' in the
'DESC' file.
'-cN'
Print N copies of each page.
'-FDIR'
Put the directory 'DIR/devNAME' in front of the search path for the
font, prologue and device description files, given the target
device NAME, usually *ps*.
'-g'
Tell the printer to guess the page length. Useful for printing
vertically centered pages when the paper dimensions are determined
at print time.
'-IPATH ...'
Consider the directory 'PATH' for searching included files
specified with relative paths. The current directory is searched
as fallback.
'-l'
Use landscape orientation.
'-m'
Use manual feed.
'-pPAPERSIZE'
Set the page dimensions. Overrides the commands 'papersize',
'paperlength', and 'paperwidth' in the 'DESC' file. See the
'groff_font(5)' manual page for details.
'-PPROLOGUE'
Use the PROLOGUE in the font path as the prologue instead of the
default 'prologue'. Overrides the environment variable
'GROPS_PROLOGUE'.
'-wN'
Set the line thickness to N/1000em. Overrides the default value N
= 40.
