|
|
* 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.
