usage="Usage: $prog [OPTION]... PACKAGE MANUAL-TITLE

Generate output in various formats from PACKAGE.texinfo (or .texi or
.txi) source.  See the GNU Maintainers document for a more extensive
discussion:
  http://www.gnu.org/prep/maintain_toc.html

Options:
  -s SRCFILE  read Texinfo from SRCFILE, instead of PACKAGE.{texinfo|texi|txi}
  -o OUTDIR   write files into OUTDIR, instead of manual/.
  --email ADR use ADR as contact in generated web pages.
  --docbook   convert to DocBook too (xml, txt, html, pdf and ps).
  --html ARG  pass indicated ARG to makeinfo or texi2html for HTML targets.
  --info ARG  pass indicated ARG to makeinfo for Info, instead of --no-split.
  --texi2html use texi2html to generate HTML targets.
  --help      display this help and exit successfully.
  --version   display version information and exit successfully.

Simple example: $prog --email bug-gnu-emacs@gnu.org emacs \"GNU Emacs Manual\"

Typical sequence:
  cd PACKAGESOURCE/doc
  wget \"$scripturl\"
  wget \"$templateurl\"
  $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"

Output will be in a new subdirectory \"manual\" (by default;
use -o OUTDIR to override).  Move all the new files into your web CVS
tree, as explained in the Web Pages node of maintain.texi.

Please do use the --email ADDRESS option to specify your bug-reporting
address in the generated HTML pages.

MANUAL-TITLE is included as part of the HTML <title> of the overall
manual/index.html file.  It should include the name of the package being
documented.  manual/index.html is created by substitution from the file
$GENDOCS_TEMPLATE_DIR/gendocs_template.  (Feel free to modify the
generic template for your own purposes.)

If you have several manuals, you'll need to run this script several
times with different MANUAL values, specifying a different output
directory with -o each time.  Then write (by hand) an overall index.html
with links to them all.

If a manual's Texinfo sources are spread across several directories,
first copy or symlink all Texinfo sources into a single directory.
(Part of the script's work is to make a tar.gz of the sources.)

As implied above, by default monolithic Info files are generated.
If you want split Info, or other Info options, use --info to override.

You can set the environment variables MAKEINFO, TEXI2DVI, TEXI2HTML, and
DVIPS to control the programs that get executed, and
GENDOCS_TEMPLATE_DIR to control where the gendocs_template file is
looked for.  With --docbook, the environment variables DOCBOOK2HTML,
DOCBOOK2PDF, DOCBOOK2PS, and DOCBOOK2TXT are also respected.

By default, makeinfo and texi2dvi are run in the default (English)
locale, since that's the language of most Texinfo manuals.  If you
happen to have a non-English manual and non-English web site, see the
SETLANG setting in the source.

Email bug reports or enhancement requests to bug-texinfo@gnu.org.
