DESCRIPTION

</P>


<P>grog reads files and guesses which of the groff(1) options
_e, _man, _me, _mm, _ms, _p, _s,and _t are required for
printing files, and prints the groff command including those options on the standard output. A filename of
_ is taken to refer to the standard input. If no files are specified, the standard input will be read. Any specified options will be included in the
printed command. No space is allowed between options and their arguments. For example,
<!-- CODE SNIP //-->
<PRE>
`grog _Tdvi paper.ms'
</PRE>
<!-- END CODE SNIP //-->
will guess the appropriate command to print
paper.ms and then run it after adding the _Tdvi option.

DESCRIPTION
</B>
</P>



<P>grops translates the output of GNU troff to PostScript. Normally,
grops should be invoked by using the groff command with a
_Tps option. If no files are given, grops will read the standard input. A filename of
_ will also cause grops to read the standard input. PostScript output is written to the standard output. When
grops is run by groff, options can be passed to
grops by using the groff _P option.

<TABLE>

<TR><TD>
_bn
</TD><TD>
Work around broken spoolers and previewers. Normally
grops produces output that conforms the Document Structuring Conventions version 3.0. Unfortunately, some spoolers and previewers can't handle such output.
The value of n controls what grops does to its output acceptable to such programs. A value of
0 will cause grops not to employ any workarounds. Add
1 if no %%BeginDocumentSetup and
%%EndDocumentSetup comments should be generated; this is needed for early versions of TranScript that get confused by anything between the
%%EndProlog comment and the first %%Page comment. Add
2 if lines in included files beginning with %! should be stripped
out; this is needed for Sun's pageview previewer. Add
4 if %%Page, %%Trailer, and %%EndProlog comments should
be stripped out of included files; this is needed for spoolers that don't understand the
%%BeginDocument and %%EndDocument comments. Add 8 if the first line of the PostScript output should be
%!PS-Adobe-2.0 rather than %!PS-Adobe-3.0; this is needed when using Sun's Newsprint with a printer that requires page reversal. The
default value can be specified by a brokenn command in the
DESC file. Otherwise, the default value is 0.
</TD></TR><TR><TD>
_cn
</TD><TD>
Print n copies of each page.
</TD></TR><TR><TD>
_g
</TD><TD>
Guess the page length. This generates PostScript code that guesses the page length. The guess will be correct
only if the imageable area is vertically centered on the page. This option allows you to generate documents that can
be printed both on letter (8.5&#165;11) paper and on A4 paper without change.
</TD></TR><TR><TD>
_l
</TD><TD>
Print the document in landscape format.
</TD></TR><TR><TD>
_Fdir
</TD><TD>
Search the directory dir/devname for font and device description files;
name is the name of the device, usually ps.
</TD></TR><TR><TD>
_wn
</TD><TD>
Lines should be drawn using a thickness of
n thousandths of an em.
</TD></TR><TR><TD>
_v
</TD><TD>
Print the version number.
