-usage="Usage: $program [OPTION]... FILE...
-
-Run each Texinfo or LaTeX FILE through TeX in turn until all
-cross-references are resolved, building all indices. The directory
-containing each FILE is searched for included files. The suffix of FILE
-is used to determine its language (LaTeX or Texinfo).
-
-Makeinfo is used to perform Texinfo macro expansion before running TeX
-when needed.
-
-Operation modes:
- -b, --batch no interaction
- -c, --clean remove all auxiliary files
- -D, --debug turn on shell debugging (set -x)
- -h, --help display this help and exit successfully
- -o, --output=OFILE leave output in OFILE (implies --clean);
- Only one input FILE may be specified in this case
- -q, --quiet no output unless errors (implies --batch)
- -s, --silent same as --quiet
- -v, --version display version information and exit successfully
- -V, --verbose report on what is done
-
-TeX tuning:
- -@ use @input instead of \input; for preloaded Texinfo
- -e, -E, --expand force macro expansion using makeinfo
- -I DIR search DIR for Texinfo files
- -l, --language=LANG specify the LANG of FILE (LaTeX or Texinfo)
- -p, --pdf use pdftex or pdflatex for processing
- -r, --recode call recode before TeX to translate input characters
- -t, --command=CMD insert CMD in copy of input file
- or --texinfo=CMD multiple values accumulate
-
-The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
-TEX (or PDFTEX), TEXINDEX, and THUMBPDF environment variables are used
-to run those commands, if they are set. Any CMD strings are added
-after @setfilename for Texinfo input, in the first line for LaTeX input.
-
-Email bug reports to <bug-texinfo@gnu.org>,
-general questions and discussion to <help-texinfo@gnu.org>.
