-usage="Usage: $program [OPTION]... FILE...
-
-Run each Texinfo or (La)TeX 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 ((La)TeX or Texinfo).  To process
-(e)plain TeX files, set the environment variable LATEX=tex.
-
-In order to make texi2dvi a drop-in replacement of TeX/LaTeX in AUC-TeX,
-the FILE may also be composed of the following simple TeX commands.
-  \`\\input{FILE}'     the actual file to compile
-  \`\\nonstopmode'     same as --batch
-
-Makeinfo is used to perform Texinfo macro expansion before running TeX
-when needed.
-
-General options:
-  -b, --batch         no interaction
-  -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
-      --dvi                  output a DVI file [default]
-  -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)
-      --no-line-error        do not pass --file-line-error to TeX
-  -p, --pdf                  use pdftex or pdflatex for processing
-  -r, --recode               call recode before TeX to translate input
-      --recode-from=ENC      recode from ENC to the @documentencoding
-      --src-specials         pass --src-specials to TeX
-  -t, --command=CMD          insert CMD in copy of input file
-   or --texinfo=CMD          multiple values accumulate
-      --translate-file=FILE  use given charset translation file for TeX
-
-Build modes:
-  --build=MODE         specify the treatment of auxiliary files [$build_mode]
-      --tidy           same as --build=tidy
-  -c, --clean          same as --build=clean
-      --build-dir=DIR  specify where the tidy compilation is performed;
-			 implies --tidy;
-			 defaults to TEXI2DVI_BUILD_DIRECTORY [$build_dir]
-  --mostly-clean       remove the auxiliary files and directories
-			 but not the output
-
-The MODE specifies where the TeX compilation takes place, and, as a
-consequence, how auxiliary files are treated.  The build mode
-can also be set using the environment variable TEXI2DVI_BUILD_MODE.
-
-Valid MODEs are:
-  \`local'      compile in the current directory, leaving all the auxiliary
-	       files around.  This is the traditional TeX use.
-  \`tidy'       compile in a local *.t2d directory, where the auxiliary files
-	       are left.  Output files are copied back to the original file.
-  \`clean'      same as \`tidy', but remove the auxiliary directory afterwards.
-	       Every compilation therefore requires the full cycle.
-
-Using the \`tidy' mode brings several advantages:
-  -   the current directory is not cluttered with plethora of temporary files.
-  -   clutter can be even reduced using --build-dir=dir: all the *.t2d
-      directories are stored there.
-  -   clutter can be reduced to zero using, e.g., --build-dir=/tmp/\$USER.t2d
-      or --build-dir=\$HOME/.t2d.
-  -   the output file is updated after every succesful TeX run, for
-      sake of concurrent visualization of the output.  In a \`local' build
-      the viewer stops during the whole TeX run.
-  -   if the compilation fails, the previous state of the output file
-      is preserved.
-  -   PDF and DVI compilation are kept in separate subdirectories
-      preventing any possibility of auxiliary file incompatibility.
-
-On the other hand, because \`tidy' compilation takes place in another
-directory, occasionally TeX won't be able to find some files (e.g., when
-using \\graphicspath): in that case use -I to specify the additional
-directories to consider.
-
-The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
-TEX (or PDFTEX), TEXINDEX, and THUMBPDF environment variables are used
-to run those commands, if they are set.  Any CMD strings are added
-after @setfilename for Texinfo input, in the first line for LaTeX input.
