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