+\slide{Introduction}
+\LogoOn
+gnome-internet-radio-locator is a Free Software program that allows computer users
+to easily locate and listen to radio programs on broadcasters on the Internet
+such as BBC, KEXP and WMBR, as well as NASA's Third Rock Station and 104 other
+Internet Radio stations broadcasting from many universities around the world.
+
+gnome-internet-radio-locator is developed for the GNOME 3.34 desktop and requires
+gst-player from gstreamer (\url{https://gstreamer.freedesktop.org/}) to be installed for audio playback.
+
+gnome-internet-radio-locator is not officially a part of GNU or GNOME,
+but using the *.gnome.org infrastructure on\\
+\url{http://gitlab.gnome.org/GNOME/gnome-internet-radio-locator} and\\
+\url{https://download.gnome.org/sources/gnome-internet-radio-locator/}
+
+\slide{Why do I write gnome-internet-radio-locator?}
+
+\begin{list1}
+\item I am a supporter of
+  \begin{list2}
+  \item Free Radio
+  \item Free Software
+  \item Free Speech
+  \end{list2}
+\item I want to give something back to the Free Software community
+\item Internet Radio is a free Internet resource
+\item Many Universities run non-profit Internet radio stations
+\end{list1}

+
+\slide{What is the definition of Free Software?}
+
+From FSF's home page (\url{https://www.gnu.org/philosophy/free-sw.html}):
+
+\begin{list1}
+\item Free Software is a good idea because you have
+  \begin{list2}
+    \item The freedom to run the program as you wish, for any purpose (freedom 0).
+    \item The freedom to study how the program works, and change it so it does your computing as you wish 
(freedom 1). Access to the source code is a precondition for this.
+    \item The freedom to redistribute copies so you can help your neighbor (freedom 2).
+    \item The freedom to distribute copies of your modified versions to others (freedom 3). By doing this 
you can give the whole community a chance to benefit from your changes. Access to the source code is a 
precondition for this.
+  \end{list2}
+\end{list1}
+
+\slide{Existing Music Services}
+
+\begin{list1}
+\item Apple Music, Google Music and Spotify
+  \begin{list2}
+  \item Require non-free client software
+  \item DRM (Digital Restrictions Management)
+  \item Impose EULAs that restrict more than copyright
+  \item Track what the user listens to
+  \end{list2}
+\end{list1}
+
+One redeeming feature of some of them:
+
+\begin{list2}
+\item You can't access them from GNU/Linux at all.  If you're a GNU/Linux user, this protects you from the 
temptation to use them.
+\end{list2}
+
+\slide{Why did I write gnome-internet-radio-locator?}

+The first public talk I gave in the UK, was a talk on Music Recording, Production and Distribution with Free 
Software at
