* initramfs-tools-hook: Bug fix: Make sure the right version of GnuPG
                        is copied into the initramfs image.  Always
                        assume that GPGME is used to avoid searching
                        for it since the path might not be /usr/lib.
                        Thanks to Félix Sipma <felix+debian@gueux.org>
                        for the initial bug report, and also thanks to
                        Dick Middleton <dick@lingbrae.com> for some
                        more debugging.
* initramfs-unpack: New script to help with development and debugging.
                    It is only part of the source tree, it is not
                    installed.
