These lines are formatted as described above. The output from this filter can be passed to troff(1) for output. There need be no particular ordering with eqn(1) or tbl(1).
In regular mode vgrind accepts input files, processes them, and passes them to the postprocessor for output, psroff(1) by default.
In both modes vgrind passes any lines beginning with a decimal point without conversion.
The options are:
forces input to be taken from standard input (default if -f is specified)
-W
forces output to the (wide) Versatec printer rather than the (narrow) Varian
-d file
specifies an alternate language definitions file (default is /usr/share/misc/vgrindefs)
-f
forces filter mode
-h header
specifies a particular header to put on every output page (default is the file name)
-l
specifies the language to use. Currently known are PASCAL (-lp), MODEL (-lm), C (-l c or the default), C++ (-lc++), CSH (-lcsh), SHELL (-lsh), RATFOR (-lr), MODULA2 (-lmod2), YACC (-lyacc), LISP (-lisp), ICON (-lI), and PERL (-lperl).
-n
forces no keyword bolding
-p postproc
use postproc to post-process the output, psroff(1) by default.
-s
specifies a point size to use on output (exactly the same as the argument of a .ps)
-t
similar to the same option in troff(1) causing formatted text to go to the standard output
-x
outputs the index file in a pretty format. The index file itself is produced whenever vgrind is run with a file called index in the current directory. The index of function definitions can then be run off by giving vgrind the -x option and the file index as argument.
