39 usage
="Usage: $program [OPTION]... FILE...
41 Run each Texinfo or LaTeX FILE through TeX in turn until all
42 cross-references are resolved, building all indices. The directory
43 containing each FILE is searched for included files. The suffix of FILE
44 is used to determine its language (LaTeX or Texinfo).
46 Makeinfo is used to perform Texinfo macro expansion before running TeX
50 -@ Use @input instead of \input; for preloaded Texinfo.
51 -b, --batch No interaction.
52 -c, --clean Remove all auxiliary files.
53 -D, --debug Turn on shell debugging (set -x).
54 -e, --expand Force macro expansion using makeinfo.
55 -I DIR Search DIR for Texinfo files.
56 -h, --help Display this help and exit successfully.
57 -l, --language=LANG Specify the LANG of FILE: LaTeX or Texinfo.
58 -p, --pdf Use pdftex or pdflatex for processing.
59 -q, --quiet No output unless errors (implies --batch).
60 -s, --silent Same as --quiet.
61 -t, --texinfo=CMD Insert CMD after @setfilename in copy of input file.
62 Multiple values accumulate.
63 -v, --version Display version information and exit successfully.
64 -V, --verbose Report on what is done.
66 The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
67 TEX (or PDFTEX), and TEXINDEX environment variables are used to run
68 those commands, if they are set.
