1 To make troff (actually a.out): 2 3 make 4 5 You will also need to write a driver for your favorite output device. 6 d202.c provides a model, although it is specialized to a machine no 7 one has. There are also a variety of postscript drivers that are the 8 best thing to use if you have a postscript device. 9 10 You will also have to make a DESC file for your typesetter and some 11 font description files; see dev202 for examples. These describe the 12 named characters, widths, kerning information, and output codes. 13 14 Nroff is the same program as troff, so you should 15 16 cp a.out /usr/bin/troff 17 ln /usr/bin/troff /usr/bin/nroff 18 19 or the equivalent. 20 21 You will also need terminal description files for your terminals; see 22 tab.37, tab.450 and tab.lp for examples. 23 24 Troff uses files that are normally stored in /usr/lib/font; 25 macro packages are in /usr/lib/tmac; and nroff tables are in 26 /usr/lib/term. You can edit tdef.h to change these assumptions. 27 28 There have been a few features since the last version, and a number of 29 significant internal changes. Not all are improvements, of course. 30 Most of the more recent changes, including bug fixes, are in FIXES, 31 which you should read also.
