+usage="Usage: $prog [OPTION]... PACKAGE MANUAL-TITLE
+
+Generate various output 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:
+  -o OUTDIR   write files into OUTDIR, instead of manual/.
+  --docbook   convert to DocBook too (xml, txt, html, pdf and ps).
+  --html ARG  pass indicated ARG to makeinfo for HTML targets.
+  --help      display this help and exit successfully.
+  --version   display version information and exit successfully.
+
+Simple example: $prog emacs \"GNU Emacs Manual\"
+
+Typical sequence:
+  cd YOURPACKAGESOURCE/doc
+  wget \"$scripturl\"
+  wget \"$templateurl\"
+  $prog YOURMANUAL \"GNU YOURMANUAL - One-line description\"
+
+Output will be in a new subdirectory \"manual\" (by default, use -o OUTDIR
+to override).  Move all the new files into your web CVS tree, as
+explained in the Web Pages node of maintain.texi.
+
+MANUAL-TITLE is included as part of the HTML <title> of the overall
+manual/index.html file.  It should include the name of the package being
+documented.  manual/index.html is created by substitution from the file
+$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 YOURMANUAL values, specifying a different output
+directory with -o each time.  Then write (by hand) an overall index.html
+with links to them all.
+
+You can set the environment variables MAKEINFO, TEXI2DVI, and DVIPS to
+control the programs that get executed, and GENDOCS_TEMPLATE_DIR to
+control where the gendocs_template file is looked for.
+
+Email bug reports or enhancement requests to bug-texinfo@gnu.org.
