-\textit{Python}\cite{Python}. The main module can,
-and is, be embedded in an apache
-webserver\footnote{\url{https://httpd.apache.org/}} via the
-\textit{mod\_python} apache module\cite{Modpython}. The module
-\textit{mod\_python} allows the webserver to execute Python code in
-the webserver. We chose Python because of the rich set of standard libraries
-and solid cross platform capabilities. We chose Python 2 because it is still
-the default Python version on all major operating systems and stays supported
-until at least the year 2020 meaning that the program can function safe at
-least 5 full years. The application consists of a main Python module that is
-embedded in the webserver. Finally there are some libraries and there is a
-standalone program that does the periodic crawling.
