# Ubuntu's roundcube-core has dependencies on Apache & MySQL, which we don't want, so we can't
# install roundcube directly via apt-get install. We'll use apt-get to manually install the
# dependencies of roundcube that we know we need, and then we'll manually install debs for
# roundcube using dpkg so that dependencies aren't triggered.

# These dependencies are from 'apt-cache showpkg roundcube-core'.
