Updated Apache vhost snippet examples to include Listen directives and to remove https schema from the ssl snippet. The generated vhost conf files are now directly usable on Gentoo "as is" by doing: $ ln -s /opt/cds-invenio/etc/apache/invenio-apache-vhost.conf /etc/apache2/vhosts.d/invenio-apache-vhost.conf $ ln -s /opt/cds-invenio/etc/apache/invenio-apache-vhost-ssl.conf /etc/apache2/vhosts.d/invenio-apache-vhost-ssl.conf
