+ \`\\input{FILE}' the actual file to compile
+ \`\\nonstopmode' same as --batch
Makeinfo is used to perform Texinfo macro expansion before running TeX
when needed.
-Operation modes:
+General options:
-b, --batch no interaction
- -c, --clean remove all auxiliary files
-D, --debug turn on shell debugging (set -x)
-h, --help display this help and exit successfully

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 the LANG of FILE (LaTeX or Texinfo)

+
+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.
