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.
