Message : gnupload: moved to gnulib Since the gnupload script is not required by automake-generated code (be it configure or Makefile content), and is not specifically tied to automake in any way, it is better to have its master copy installed in the gnulib repository, as is already done for similar generally-useful, maintainer-oriented scripts. We can them sync it from there. See also gnulib commit v0.0-6822-gf8b7120, and: <http://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00222.html> * Makefile.am (FETCHFILES): Added 'gnupload'. (fetch): Also sync 'gnupload' from the gnulib repository. * lib/gnupload: Synced from gnulib. * NEWS: Update.

Sign all FILES, and process them at selected destinations according to CMD.
<http://www.gnu.org/prep/maintain/html_node/Automated-FTP-Uploads.html>
explains further.

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 foobar-1.0.tar.gz to ftp.gnu.org:
  gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz

2. Upload foobar-1.0.tar.gz and foobar-1.0.tar.xz to ftp.gnu.org:
  gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz foobar-1.0.tar.xz

3. Same as above, and also create symbolic links to foobar-latest.tar.*:
  gnupload --to ftp.gnu.org:foobar \\
           --symlink-regex \\
           foobar-1.0.tar.gz foobar-1.0.tar.xz

4. Upload foobar-0.9.90.tar.gz to two sites:
  gnupload --to alpha.gnu.org:foobar \\
           --to sources.redhat.com:~ftp/pub/foobar \\
           foobar-0.9.90.tar.gz

5. Delete oopsbar-0.9.91.tar.gz and upload foobar-0.9.91.tar.gz
   (the -- terminates the list of files to delete):
  gnupload --to alpha.gnu.org:foobar \\
           --to sources.redhat.com:~ftp/pub/foobar \\
           --delete oopsbar-0.9.91.tar.gz \\
           -- foobar-0.9.91.tar.gz

gnupload uses the ncftpput program to do the transfers; if you don't
happen to have an ncftp package installed, the ncftpput-ftp script in
the build-aux/ directory of the gnulib package
(http://savannah.gnu.org/projects/gnulib) may serve as a replacement.
