81 usage="Usage: $prog [OPTION]... PACKAGE MANUAL-TITLE
83 Generate output in various formats from PACKAGE.texinfo (or .texi or
84 .txi) source. See the GNU Maintainers document for a more extensive
85 discussion:
86 https://www.gnu.org/prep/maintain_toc.html
88 Options:
89 --email ADR use ADR as contact in generated web pages; always give this.
91 -s SRCFILE read Texinfo from SRCFILE, instead of PACKAGE.{texinfo|texi|txi}
92 -o OUTDIR write files into OUTDIR, instead of manual/.
93 -I DIR append DIR to the Texinfo search path.
94 --common ARG pass ARG in all invocations.
95 --html ARG pass ARG to makeinfo or texi2html for HTML targets,
96 instead of '$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.
106 --texi2html use texi2html to make HTML target, with all split versions.
107 --docbook convert through DocBook too (xml, txt, html, pdf).
109 --help display this help and exit successfully.
110 --version display version information and exit successfully.
112 Simple example: $prog --email bug-gnu-emacs@gnu.org emacs \"GNU Emacs Manual\"
114 Typical sequence:
115 cd PACKAGESOURCE/doc
116 wget \"$scripturl\"
117 wget \"$templateurl\"
118 $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"
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.
124 Please use the --email ADDRESS option so your own bug-reporting
125 address will be used in the generated HTML pages.
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.)
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.
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.)
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.
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.
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.
