.Sh SYNOPSIS
|
||||
.Nm
|
||||
.Op Ar
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility
|
||||
reads the specified files or the standard input and performs the textual
|
||||
inclusion implied by the
|
||||
.Xr nroff 1
|
||||
directives of the form:
|
||||
.Pp
|
||||
.Dl \&.so somefile
|
||||
.Pp
|
||||
The directives need to appear at the beginning of input lines.
|
||||
This is useful since programs such as
|
||||
.Xr tbl 1
|
||||
do not normally do this; it allows the placement of individual tables
|
||||
in separate files to be run as a part of a large document.
|
||||
.Pp
|
||||
An argument consisting of a single minus
|
||||
.Sq Fl
|
||||
is taken to be
|
||||
a file name corresponding to the standard input.
|
||||
.Pp
|
||||
Note that inclusion can be suppressed by using
|
||||
.Ql \e'
|
||||
instead of
|
||||
.Ql \e. ,
|
||||
i.e.\&
|
||||
.Pp
|
||||
.Dl \'so /usr/lib/tmac.s
|
||||
.Pp
|
||||
A sample usage of
|
||||
.Nm
|
||||
would be
|
||||
.Pp

||||
.Bd -literal -offset indent -compact

The format of the source commands must involve no strangeness \-
|
||||
exactly one blank must precede and no blanks follow the file name.

* soelim - a filter to process n/troff input eliminating .so's
|

*
|
||||
* Author: Bill Joy UCB July 8, 1977
|
||||
*
|
||||
* This program eliminates .so's from a n/troff input stream.
|
||||
* It can be used to prepare safe input for submission to the
|
||||
* phototypesetter since the software supporting the operator
|
||||
* doesn't let him do chdir.
|
||||
*
|
||||
* This is a kludge and the operator should be given the
|
||||
* ability to do chdir.
|
||||
*
|
||||
* This program is more generally useful, it turns out, because
|
||||
* the program tbl doesn't understand ".so" directives.
