39: % Send bug reports to bug-texinfo@gnu.org. Please include including a

42: %
43: % To process a Texinfo manual with TeX, it's most reliable to use the
44: % texi2dvi shell script that comes with the distribution. For a simple
45: % manual foo.texi, however, you can get away with this:
46: % tex foo.texi
47: % texindex foo.??
48: % tex foo.texi
49: % tex foo.texi
1.3 ! takayama 50: % dvips foo.dvi -o # or whatever; this makes foo.ps.
! 51: % The extra TeX runs get the cross-reference information correct.
1.1 noro 52: % Sometimes one run after texindex suffices, and sometimes you need more
53: % than two; texi2dvi does it as many times as necessary.
54: %
1.3 ! takayama 55: % It is possible to adapt texinfo.tex for other languages, to some
! 56: % extent. You can get the existing language-specific files from the
! 57: % full Texinfo distribution.
