+Docker image for lurker, a mailing list archiver.
+
+The image contains both an Apache server and an incoming SMTP server,
+this is simply because the Debian lurker package has a strict dependency
+on the apache2 package, so it was more convenient to do it this way
+instead of using two separate container images.
+
+Configuration and data storage must be mounted respectively in
+*/etc/lurker* and */var/lib/lurker*.
