\section{Boot strapping the library}
Before the library can be started the available widgets and windows need to
be registered. This registering is done before \textsc{main()} is started.
The registering is done by some small static classes that do the registering
of the item\footnote{Widget or Window.} in its constructor. Since this
involves some redundant typing there are REGISTER\_XXX macros written.
After all items are register the library can be started, which is simply
done by \textsc{gui2::init()}. This function does all required steps to get
the library up and running.
\section{Layout algorithm}
An important part of the gui engine is to properly layout the widgets in the
available space. The documentation of that algorithm is written in
doxygen\footnote{\url{http://devdocs.wesnoth.org/layout_algorihm.html}}.
