# Make auxiliary documentation using nroff and LaTeX.  makeindex.l is
# the nroff/troff input file for the UNIX manual pages.  From it, we
# produce:
#	makeindex.hlp (printable ASCII help file),
#	makeindex.info (GNU Emacs INFO node file),
#	makeindex.ps (PostScript version of typeset manual pages), and
#	makeindex.vms (VAX VMS hierarchical help file),
#	manpages.dvi (.dvi file of manual pages)

#	on AIX: tbl | eqn | psroff -t -man | psrev

# We create a .dvi file for the manual pages under a different name to
# avoid a collision with makeindex.dvi.  GNU groff works quite nicely,
# and gives us a .dvi file that anyone can process, even if they do not
# have a PostScript printer.  groff's font selection is a bit unusual;
# it wants a few Computer Modern fonts in magnifications 0.8 and 0.9.
# For manpages.dvi, it needs these additional font files: cmbx10.240pk
# cmbx10.270pk cmcsc10.240pk cmcsc10.270pk cmr10.240pk cmr10.270pk
# cmti10.240pk cmti10.270pk.  If your DVI driver can substitute a nearby
# size, you should be able to manage without them.
