50: * Author: Bill Joy UCB July 8, 1977
51: *
52: * This program eliminates .so's from a n/troff input stream.
53: * It can be used to prepare safe input for submission to the
54: * phototypesetter since the software supporting the operator
55: * doesn't let him do chdir.
56: *
57: * This is a kludge and the operator should be given the
58: * ability to do chdir.
59: *
60: * This program is more generally useful, it turns out, because
61: * the program tbl doesn't understand ".so" directives.
