| 36 | usage="Usage: $program [OPTION]... FILE...
|
|---|
| 37 |
|
|---|
| 38 | Run each Texinfo or LaTeX FILE through TeX in turn until all
|
|---|
| 39 | cross-references are resolved, building all indices. The directory
|
|---|
| 40 | containing each FILE is searched for included files. The suffix of FILE
|
|---|
| 41 | is used to determine its language (LaTeX or Texinfo).
|
|---|
| 42 |
|
|---|
| 43 | Makeinfo is used to perform Texinfo macro expansion before running TeX
|
|---|
| 44 | when needed.
|
|---|
| 45 |
|
|---|
| 46 | Operation modes:
|
|---|
| 47 | -b, --batch no interaction
|
|---|
| 48 | -c, --clean remove all auxiliary files
|
|---|
| 49 | -D, --debug turn on shell debugging (set -x)
|
|---|
| 50 | -h, --help display this help and exit successfully
|
|---|
| 51 | -o, --output=OFILE leave output in OFILE (implies --clean);
|
|---|
| 52 | Only one input FILE may be specified in this case
|
|---|
| 53 | -q, --quiet no output unless errors (implies --batch)
|
|---|
| 54 | -s, --silent same as --quiet
|
|---|
| 55 | -v, --version display version information and exit successfully
|
|---|
| 56 | -V, --verbose report on what is done
|
|---|
| 57 |
|
|---|
| 58 | TeX tuning:
|
|---|
| 59 | -@ use @input instead of \input; for preloaded Texinfo
|
|---|
| 60 | -e, -E, --expand force macro expansion using makeinfo
|
|---|
| 61 | -I DIR search DIR for Texinfo files
|
|---|
| 62 | -l, --language=LANG specify the LANG of FILE (LaTeX or Texinfo)
|
|---|
| 63 | -p, --pdf use pdftex or pdflatex for processing
|
|---|
| 64 | -t, --texinfo=CMD insert CMD after @setfilename in copy of input file
|
|---|
| 65 | multiple values accumulate
|
|---|
| 66 |
|
|---|
| 67 | The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
|
|---|
| 68 | TEX (or PDFTEX), and TEXINDEX environment variables are used to run
|
|---|
| 69 | those commands, if they are set.
