/*
* 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.
