As the VCS repository on the invent.kde.org GitLab instance for the
KDEmail.net website is likely to experience more frequent changes, it is
foreseeable that some web search engines will rank it equally or even
superior to the static documentation site proper.

Those page hits present no less an opportunity to inform visitors with
an expressed curiosity in the KDEmail.net service. The AsciiDoc README
file, which GitLab automatically renders to HTML5, duplicates index.html
as far as the parser will allow.
