+
+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.

+# In case `local' is not supported by the shell, provide a function

+# does make sure there is never twice a static local declaration of a

+# Note that since we might use a function simulating `local', we can
