+Usage: $program [OPTION]... FILE...
+ or: texi2pdf [OPTION]... FILE...
+ or: pdftexi2dvi [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
+
+When invoked as \`texi2pdf' or \`pdftexi2dvi', or given the option --pdf
+or --dvipdf, generate PDF output. Otherwise, generate DVI.
+
+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; only one input FILE is allowed
+ -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
+
+Output format:
+ --dvi output a DVI file [default]
+ --dvipdf output a PDF file via DVI (using a dvi-to-pdf program)
+ --html output an HTML file from LaTeX, using HeVeA
+ --info output an Info file from LaTeX, using HeVeA
+ -p, --pdf use pdftex or pdflatex for processing
+ --ps output a PostScript file via DVI (using dvips)
+ --text output a plain text file from LaTeX, using HeVeA
+
+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 LANG for FILE, either latex or texinfo
+ --no-line-error do not pass --file-line-error to TeX
+ --shell-escape pass --shell-escape to TeX
+ --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 [$build_dir]
+ --mostly-clean remove the auxiliary files and directories
+ but not the output
+ --max-iterations=N don't process files more than N times [$max_iters]
+
+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 further 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 successful 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 BIBER, BIBTEX, DVIPDF, DVIPS, HEVEA, LATEX, MAKEINDEX,
+MAKEINFO, PDFLATEX, PDFTEX, SED, T4HT, TEX, TEX4HT, TEXINDEX, and THUMBPDF_CMD
+environment variables are used to run those commands, if they are set.
+
+Regarding --dvipdf, if DVIPDF is not set in the environment, the
+following programs are looked for (in this order): dvipdfmx dvipdfm
+dvipdf dvi2pdf dvitopdf.
+
+Any CMD strings are added after @setfilename for Texinfo input, or in
+the first line for LaTeX input.
