46 | * soelim - a filter to process n/troff input eliminating .so's | |
47 | * | |
48 | * Author: Bill Joy UCB July 8, 1977 | |
49 | * | |
50 | * This program eliminates .so's from a n/troff input stream. | |
51 | * It can be used to prepare safe input for submission to the | |
52 | * phototypesetter since the software supporting the operator | |
53 | * doesn't let him do chdir. | |
54 | * | |
55 | * This is a kludge and the operator should be given the | |
56 | * ability to do chdir. | |
57 | * | |
58 | * This program is more generally useful, it turns out, because | |
59 | * the program tbl doesn't understand ".so" directives. | |
