    <!-- Helper Ant script to perform a release of GwtBootstrap3.

         Everything needs to be set up as described here:
         https://docs.sonatype.org/display/Repository/Sonatype+OSS+Maven+Repository+Usage+Guide

         This script assumes that it's executed in a directory where gwtbootstrap3 is checked out to a directory named
         "gwtbootstrap3" and gwtbootstrap3-extras is checked out to "gwtbootstrap3-extras".

         In order for the script to work the GPG passphrase of your key for release signing needs to be specified in
         Maven's ~/.m2/settings.xml because it cannot be entered interactively when Maven is executed by Ant nor can
         it be specified by command line arguments. That's an issue of Maven's release plugin.
