  32 # - image importing was only implemented for HTML generated by
  33 #   makeinfo.  But it should be simple enough to adjust.
  34 # - images are not imported in the source tarball.  All the needed
  35 #   formats (PDF, PNG, etc.) should be included.

  83 Generate output in various formats from PACKAGE.texinfo (or .texi or
  84 .txi) source.  See the GNU Maintainers document for a more extensive
  85 discussion:
  86   https://www.gnu.org/prep/maintain_toc.html
  87
  88 Options:
  89   --email ADR use ADR as contact in generated web pages; always give this.
  90
  91   -s SRCFILE   read Texinfo from SRCFILE, instead of PACKAGE.{texinfo|texi|txi}
  92   -o OUTDIR    write files into OUTDIR, instead of manual/.
  93   -I DIR       append DIR to the Texinfo search path.
  94   --common ARG pass ARG in all invocations.
  95   --html ARG   pass ARG to makeinfo or texi2html for HTML targets,
  96                  instead of '$htmlarg'.
  97   --info ARG   pass ARG to makeinfo for Info, instead of --no-split.
  98   --no-ascii   skip generating the plain text output.
  99   --no-html    skip generating the html output.
 100   --no-info    skip generating the info output.
 101   --no-tex     skip generating the dvi and pdf output.
 102   --source ARG include ARG in tar archive of sources.
 103   --split HOW  make split HTML by node, section, chapter; default node.
 104   --tex ARG    pass ARG to texi2dvi for DVI and PDF, instead of -t @finalout.
 105
 106   --texi2html  use texi2html to make HTML target, with all split versions.
 107   --docbook    convert through DocBook too (xml, txt, html, pdf).
 108
 109   --help       display this help and exit successfully.
 110   --version    display version information and exit successfully.
 111
 112 Simple example: $prog --email bug-gnu-emacs@gnu.org emacs \"GNU Emacs Manual\"
 113
 114 Typical sequence:
 115   cd PACKAGESOURCE/doc
 116   wget \"$scripturl\"
 117   wget \"$templateurl\"
 118   $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"
 119
 120 Output will be in a new subdirectory \"manual\" (by default;
 121 use -o OUTDIR to override).  Move all the new files into your web CVS
 122 tree, as explained in the Web Pages node of maintain.texi.
 123
 124 Please use the --email ADDRESS option so your own bug-reporting
 125 address will be used in the generated HTML pages.
 126
 127 MANUAL-TITLE is included as part of the HTML <title> of the overall
 128 manual/index.html file.  It should include the name of the package being
 129 documented.  manual/index.html is created by substitution from the file
 130 $GENDOCS_TEMPLATE_DIR/gendocs_template.  (Feel free to modify the
 131 generic template for your own purposes.)
 132
 133 If you have several manuals, you'll need to run this script several
 134 times with different MANUAL values, specifying a different output
 135 directory with -o each time.  Then write (by hand) an overall index.html
 136 with links to them all.
 137
 138 If a manual's Texinfo sources are spread across several directories,
 139 first copy or symlink all Texinfo sources into a single directory.
 140 (Part of the script's work is to make a tar.gz of the sources.)
 141
 142 As implied above, by default monolithic Info files are generated.
 143 If you want split Info, or other Info options, use --info to override.
 144
 145 You can set the environment variables MAKEINFO, TEXI2DVI, TEXI2HTML,
 146 and PERL to control the programs that get executed, and
 147 GENDOCS_TEMPLATE_DIR to control where the gendocs_template file is
 148 looked for.  With --docbook, the environment variables DOCBOOK2HTML,
 149 DOCBOOK2PDF, and DOCBOOK2TXT are also consulted.
 150
 151 By default, makeinfo and texi2dvi are run in the default (English)
 152 locale, since that's the language of most Texinfo manuals.  If you
 153 happen to have a non-English manual and non-English web site, see the
 154 SETLANG setting in the source.
