-
-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:
- --email ADR use ADR as contact in generated web pages; always give this.
-
- -s SRCFILE read Texinfo from SRCFILE, instead of PACKAGE.{texinfo|texi|txi}
- -o OUTDIR write files into OUTDIR, instead of manual/.
- -I DIR append DIR to the Texinfo search path.
- --common ARG pass ARG in all invocations.
- --html ARG pass ARG to makeinfo or texi2html for HTML targets,
- instead of '$htmlarg'.
- --info ARG pass ARG to makeinfo for Info, instead of --no-split.
- --no-ascii skip generating the plain text output.
- --no-html skip generating the html output.
- --no-info skip generating the info output.
- --no-tex skip generating the dvi and pdf output.
- --source ARG include ARG in tar archive of sources.
- --split HOW make split HTML by node, section, chapter; default node.
- --tex ARG pass ARG to texi2dvi for DVI and PDF, instead of -t @finalout.
-
- --texi2html use texi2html to make HTML target, with all split versions.
- --docbook convert through DocBook too (xml, txt, html, pdf).
-
- --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\"
- $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"
-
-Output will be in a new subdirectory \"manual\" (by default;
-use -o OUTDIR to override). Move all the new files into your web CVS
-tree, as explained in the Web Pages node of maintain.texi.
-
-Please use the --email ADDRESS option so your own bug-reporting
-address will be used in the generated HTML pages.
-
-MANUAL-TITLE is included as part of the HTML <title> of the overall
-manual/index.html file. It should include the name of the package being
-documented. manual/index.html is created by substitution from the file
-$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 PERL 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, and DOCBOOK2TXT are also consulted.
-
-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-gnulib@gnu.org.
