| 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
 | ||
|   -t, --texinfo=CMD    insert CMD after @setfilename in copy of input file
 | ||
|                        multiple values accumulate
 | ||
| 
 | ||
| The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
 | ||
| TEX (or PDFTEX), and TEXINDEX environment variables are used to run
 | ||
| those commands, if they are set.
