+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/.
+  --email ADR use ADR as contact in generated web pages.
+  --docbook   convert to DocBook too (xml, txt, html, pdf and ps).
+  --html ARG  pass indicated ARG to makeinfo or texi2html for HTML targets.
+  --texi2html use texi2html to generate HTML targets.
+  --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\"
+  $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"
+
+Output will be in a new subdirectory \"manual\" (by default, use -o OUTDIR
+to override).  Move all the new files into your web CVS tree, as
+explained in the Web Pages node of maintain.texi.
+
+Please use the --email ADDRESS option to specify your bug-reporting
+address in the generated HTML pages.
+
+MANUAL-TITLE is included as part of the HTML <title> of the overall
+manual/index.html file.  It should include the name of the package being
+documented.  manual/index.html is created by substitution from the file
+$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.)
+
+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.  (With --docbook,
+the environment variables DOCBOOK2HTML, DOCBOOK2PDF, DOCBOOK2PS, and
+DOCBOOK2TXT are also respected.)
+
+By default, makeinfo is 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-texinfo@gnu.org.

+
+Sign all FILES, and upload them to selected destinations, according to
+<http://www.gnu.org/prep/maintain/html_node/Automated-FTP-Uploads.html>.
+
+Commands:
+  --delete                 delete FILES from destination
+  --symlink                create symbolic links
+  --rmsymlink              remove symbolic links
+  --                       treat the remaining arguments as files to upload
+
+Options:
+  --help                   print this help text and exit
+  --to DEST                specify one destination for FILES
+                           (multiple --to options are allowed)
+  --user NAME              sign with key NAME
+  --symlink-regex[=EXPR]   use sed script EXPR to compute symbolic link names
+  --dry-run                do nothing, show what would have been done
+  --version                output version information and exit
+
+If --symlink-regex is given without EXPR, then the link target name
+is created by replacing the version information with \`-latest', e.g.:
+
+  foo-1.3.4.tar.gz -> foo-latest.tar.gz
+
+Recognized destinations are:
+  alpha.gnu.org:DIRECTORY
+  savannah.gnu.org:DIRECTORY
+  savannah.nongnu.org:DIRECTORY
+  ftp.gnu.org:DIRECTORY
+                           build directive files and upload files by FTP
+  download.gnu.org.ua:{alpha|ftp}/DIRECTORY
+                           build directive files and upload files by SFTP
+  [user@]host:DIRECTORY    upload files with scp
+
+Options and commands are applied in order.  If the file $conffile exists
+in the current working directory, its contents are prepended to the
+actual command line options.  Use this to keep your defaults.  Comments
+(#) and empty lines in $conffile are allowed.
+
+Examples:
+1. Upload automake-1.8.2b.tar.gz and automake-1.8.2b.tar.bz2 to two sites:
+  gnupload --to sources.redhat.com:~ftp/pub/automake \\
+           --to alpha.gnu.org:automake \\
+           automake-1.8.2b.tar.gz automake-1.8.2b.tar.bz2
+
+2. Same as above, but also create symbolic links to automake-latest.tar.*:
+  gnupload --to sources.redhat.com:~ftp/pub/automake \\
+           --to alpha.gnu.org:automake \\
+           --symlink-regex \\
+           automake-1.8.2b.tar.gz automake-1.8.2b.tar.bz2
+
+3. Symlink automake-1.8.2b.tar.gz to automake-latest.tar.gz and
+automake-1.8.2b.tar.bz2 to automake-latest.tar.bz2 on both sites:
+
+  gnupload --to sources.redhat.com:~ftp/pub/automake \\
+           --to alpha.gnu.org:automake \\
+           --symlink automake-1.8.2b.tar.gz automake-latest.tar.gz \\
+                     automake-1.8.2b.tar.bz2 automake-latest.tar.bz2
+
+4. Delete automake-1.8.2a.tar.gz and .bz2, remove symlink
+automake-latest.tar.gz and upload automake-1.8.2b.tar.gz:
+
+  gnupload --to sources.redhat.com:~ftp/pub/automake \\
+           --to alpha.gnu.org:automake \\
+           --delete automake-1.8.2a.tar.gz automake-1.8.2a.tar.bz2 \\
+           --rmsymlink automake-latest.tar.gz \\
+           -- \\
+           automake-1.8.2b.tar.gz automake-1.8.2b.tar.bz2
