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

  64 usage="Usage: $prog [OPTION]... PACKAGE MANUAL-TITLE
  65
  66 Generate output in various formats from PACKAGE.texinfo (or .texi or
  67 .txi) source.  See the GNU Maintainers document for a more extensive
  68 discussion:
  69   http://www.gnu.org/prep/maintain_toc.html
  70
  71 Options:
  72   --email ADR use ADR as contact in generated web pages; always give this.
  73
  74   -s SRCFILE   read Texinfo from SRCFILE, instead of PACKAGE.{texinfo|texi|txi}
  75   -o OUTDIR    write files into OUTDIR, instead of manual/.
  76   -I DIR       append DIR to the Texinfo search path.
  77   --common ARG pass ARG in all invocations.
  78   --html ARG   pass ARG to makeinfo or texi2html for HTML targets.
  79   --info ARG   pass ARG to makeinfo for Info, instead of --no-split.
  80   --no-ascii   skip generating the plain text output.
  81   --source ARG include ARG in tar archive of sources.
  82   --split HOW  make split HTML by node, section, chapter; default node.
  83
  84   --texi2html  use texi2html to make HTML target, with all split versions.
  85   --docbook    convert through DocBook too (xml, txt, html, pdf).
  86
  87   --help       display this help and exit successfully.
  88   --version    display version information and exit successfully.
  89
  90 Simple example: $prog --email bug-gnu-emacs@gnu.org emacs \"GNU Emacs Manual\"
  91
  92 Typical sequence:
  93   cd PACKAGESOURCE/doc
  94   wget \"$scripturl\"
  95   wget \"$templateurl\"
  96   $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"
  97
  98 Output will be in a new subdirectory \"manual\" (by default;
  99 use -o OUTDIR to override).  Move all the new files into your web CVS
 100 tree, as explained in the Web Pages node of maintain.texi.
 101
 102 Please use the --email ADDRESS option so your own bug-reporting
 103 address will be used in the generated HTML pages.
 104
 105 MANUAL-TITLE is included as part of the HTML <title> of the overall
 106 manual/index.html file.  It should include the name of the package being
 107 documented.  manual/index.html is created by substitution from the file
 108 $GENDOCS_TEMPLATE_DIR/gendocs_template.  (Feel free to modify the
 109 generic template for your own purposes.)
 110
 111 If you have several manuals, you'll need to run this script several
 112 times with different MANUAL values, specifying a different output
 113 directory with -o each time.  Then write (by hand) an overall index.html
 114 with links to them all.
 115
 116 If a manual's Texinfo sources are spread across several directories,
 117 first copy or symlink all Texinfo sources into a single directory.
 118 (Part of the script's work is to make a tar.gz of the sources.)
 119
 120 As implied above, by default monolithic Info files are generated.
 121 If you want split Info, or other Info options, use --info to override.
 122
 123 You can set the environment variables MAKEINFO, TEXI2DVI, TEXI2HTML,
 124 and PERL to control the programs that get executed, and
 125 GENDOCS_TEMPLATE_DIR to control where the gendocs_template file is
 126 looked for.  With --docbook, the environment variables DOCBOOK2HTML,
 127 DOCBOOK2PDF, and DOCBOOK2TXT are also consulted.
 128
 129 By default, makeinfo and texi2dvi are run in the default (English)
 130 locale, since that's the language of most Texinfo manuals.  If you
 131 happen to have a non-English manual and non-English web site, see the
 132 SETLANG setting in the source.
