    docs: move some tutorial content to the reference
    
    We add a "Getting started" chapter that will grow into a
    (hopefully) non-outdated, maintained tutorial. For now, it
    includes two minimal examples by xincluding them.

-GTK+ is a library for creating graphical user interfaces. It
-works on many UNIX-like platforms, Windows, and OS X.
-GTK+ is released under the GNU Library General Public License
-(GNU LGPL), which allows for flexible licensing of client
-applications. GTK+ has a C-based object-oriented architecture that
-allows for maximum flexibility.  Bindings for many other languages have
-been written, including C++, Objective-C, Guile/Scheme, Perl, Python,
-TOM, Ada95, Free Pascal, and Eiffel.
