ghr@wucs.UUCP (George Robbert) (12/13/85)
Several people on the net have asked for the v16 GNU Emacs manuals
in nroff/troff format. I wrote a quicky program to convert from the
TeX it's distributed in to nroff/troff. I'm posting it here after
a couple of requests. It doesn't handle the fancy stuff of TeX changing
fonts and typefaces. It's just a simple lex program to produce a nroff
source for a readable manual. There also is a small C program to handle
the indecies. Btw: the nroff it produces assumes that you are using
the -me package. If you find any bugs or make any improvements on this,
Please let me know. I've also included a makefile, a file of nroff macro
definitions and a trailer file to print out the table of contents for the
GNU manual. You will probably have to modify the makefile to use the
right filenames for the GNU manual(s) and to put the nroff where you
want it.
