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