! 40:
! 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).
! 45:
! 46: Makeinfo is used to perform Texinfo macro expansion before running TeX
! 47: when needed.
! 48:
! 49: Options:
! 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.
! 65:
! 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.
