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

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
  --version                output version information and exit

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
  [user@]host:DIRECTORY    upload files with scp

Simple single-target single-file examples:
  gnupload --to alpha.gnu.org:automake automake-1.8.2b.tar.gz
  gnupload --to ftp.gnu.org:automake automake-1.8.3.tar.gz

Multiple-target multiple-file example:
  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
