53 * soelim - a filter to process n/troff input eliminating .so's
55 * Author: Bill Joy UCB July 8, 1977
57 * This program eliminates .so's from a n/troff input stream.
58 * It can be used to prepare safe input for submission to the
59 * phototypesetter since the software supporting the operator
60 * doesn't let him do chdir.
62 * This is a kludge and the operator should be given the
63 * ability to do chdir.
65 * This program is more generally useful, it turns out, because
66 * the program tbl doesn't understand ".so" directives.
