One site on two hostnames sharing the same pages: German at
<https://www.webservices-engineering.de/> and English at
<https://en.webservices-engineering.de/>. German is the x-default, and only the German
text is legally binding — the English pages are a translation. This file is served from
both hostnames and describes both.
