31: * Function: Build nroff terminal tables in a compiler-independent way.
32: * Usage: cc -Itroff mktab.c tabnnn.c -o mktab; mktab > tabnnn
33: * Date: Sat Feb 25 00:10:06 MST 1989
34: * Author: Donn Seeley
35: * Remarks:
36: * Traditional nroff terminal table construction works by compiling
37: * a C file into a binary that is read directly into nroff as it runs.
38: * If your C compiler or your relocation format differ from what nroff
39: * expects, you lose. This program, when linked with a terminal table
40: * object file, fakes up an 'object' file that looks enough like the
41: * traditional one to fool nroff.
