# In the interest of general portability, some common bourne shell
# constructs were avoided because they weren't guaranteed to be available
# in some earlier implementations. I've tried to make this program as
# portable as possible. Welcome to unix, where the lowest common
# denominator is rapidly diminishing.
#
# Among the more interesting lossages I noticed among Bourne shells:
# * No shell functions.
# * No `unset' builtin.
# * `shift' cannot take a numeric argument, and signals an error if
# there are no arguments to shift.

Run each Texinfo or LaTeX 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 (LaTeX or Texinfo).
Makeinfo is used to perform Texinfo macro expansion before running TeX
when needed.
Options:
-@ Use @input instead of \input; for preloaded Texinfo.
-b, --batch No interaction.
-c, --clean Remove all auxiliary files.
-D, --debug Turn on shell debugging (set -x).
-e, --expand Force macro expansion using makeinfo.
-I DIR Search DIR for Texinfo files.
-h, --help Display this help and exit successfully.
-l, --language=LANG Specify the LANG of FILE: LaTeX or Texinfo.
-p, --pdf Use pdftex or pdflatex for processing.
-q, --quiet No output unless errors (implies --batch).
-s, --silent Same as --quiet.
-t, --texinfo=CMD Insert CMD after @setfilename in copy of input file.
Multiple values accumulate.
-v, --version Display version information and exit successfully.
-V, --verbose Report on what is done.
The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
TEX (or PDFTEX), and TEXINDEX environment variables are used to run
those commands, if they are set.
