Hi.  Thank you for reviewing this.

Okay.  The package provides non-emacs tools too, but I agree
emacs-eweouz is more appropriate since few are likely to use the tools
outside of the Emacs context.

I re-enabled the tests now.  Upstream doesn't ship any tests, but at
least we shouldn't disable them in case there is ever a new version that
adds self-test.

It appears to be needed.  The eweouz tarball contains autogen.sh:

aclocal
autoheader
automake --copy --add-missing --foreign
autoconf
./configure --enable-maintainer-mode "$@"

And guix build seems to prefer invoking autogen.sh over autoreconf,
which causes this failure:

starting phase `bootstrap'
running './autogen.sh'
patch-shebang: ./autogen.sh: changing `/bin/sh' to `/gnu/store/4y5m9lb8k3qkb1y9m02sw9w9a6hacd16-bash-minimal-5.1.8/bin/sh'
configure.ac:10: installing './compile'
configure.ac:4: installing './install-sh'
configure.ac:4: installing './missing'
src/Makefile.am: installing './depcomp'
./autogen.sh: ./configure: /bin/sh: bad interpreter: No such file or directory
error: in phase 'bootstrap': uncaught exception:

Nice catch, fixed.

The majority is GPLv2-only.  The essential files in eweouz are the
following:

src/eweouz-dump-addressbook.c    GPLv2-only
src/eweouz-write-addressbook.c   GPLv2-only
lisp/eweouz.el                   GPLv2-only
lisp/vcard.el                    GPLv2+

Is there a way to express that?  I can't seem to find any documentation
for the (license...) clause (or am I missing it?), but I added both
licenses now and a comment.
