38: usage="Usage: $program [OPTION]... FILE...
39:
40: Run each Texinfo or LaTeX FILE through TeX in turn until all
41: cross-references are resolved, building all indices. The directory
42: containing each FILE is searched for included files. The suffix of FILE
43: is used to determine its language (LaTeX or Texinfo).
44:
45: Makeinfo is used to perform Texinfo macro expansion before running TeX
46: when needed.
47:
48: Operation modes:
49: -b, --batch no interaction
50: -c, --clean remove all auxiliary files
51: -D, --debug turn on shell debugging (set -x)
52: -h, --help display this help and exit successfully
53: -o, --output=OFILE leave output in OFILE (implies --clean);
54: Only one input FILE may be specified in this case
55: -q, --quiet no output unless errors (implies --batch)
56: -s, --silent same as --quiet
57: -v, --version display version information and exit successfully
58: -V, --verbose report on what is done
59:
60: TeX tuning:
61: -@ use @input instead of \input; for preloaded Texinfo
62: -e, -E, --expand force macro expansion using makeinfo
63: -I DIR search DIR for Texinfo files
64: -l, --language=LANG specify the LANG of FILE (LaTeX or Texinfo)
65: -p, --pdf use pdftex or pdflatex for processing
66: -t, --texinfo=CMD insert CMD after @setfilename in copy of input file
67: multiple values accumulate
68:
69: The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
70: TEX (or PDFTEX), and TEXINDEX environment variables are used to run
71: those commands, if they are set.
72:

74: general questions and discussion to <help-texinfo@gnu.org>.
