40 * soelim - a filter to process n/troff input eliminating .so's
42 * Author: Bill Joy UCB July 8, 1977
44 * This program eliminates .so's from a n/troff input stream.
45 * It can be used to prepare safe input for submission to the
46 * phototypesetter since the software supporting the operator
47 * doesn't let him do chdir.
49 * This is a kludge and the operator should be given the
50 * ability to do chdir.
52 * This program is more generally useful, it turns out, because
53 * the program tbl doesn't understand ".so" directives.
