+ <p>Linux desktop systems
+<a href="https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html">have
+standardized</a> how programs present themselves to the desktop
+system. If a package include a .desktop file in
+/usr/share/applications/, Gnome, KDE, LXDE, Xfce and the other desktop
+environments will pick up the file and use its content to generate the
+menu of available programs in the system. A lesser known fact is that
+a package can also explain to the desktop system how to recognize the
+files created by the program in question, and use it to open these
+files on request, for example via a GUI file browser.</p>
+
+<p>A while back I ran into a package that did not tell the desktop
+system how to recognize its files and was not used to open its files
+in the file browser and fixed it. In the process I wrote a simple
+debian/tests/ script to ensure the setup keep working. It might be
+useful for other packages too, to ensure any future version of the
+package keep handling its own files.</p>
+
+<p>For this to work the file format need a useful MIME type that can
+be used to identify the format. If the file format do not yet have a
+MIME type, it should define one and preferably also
+<a href="https://www.iana.org/assignments/media-types/media-types.xhtml">register
+it with IANA</a> to ensure the MIME type string is reserved.</p>
+
+<p>The script uses the <tt>xdg-mime</tt> program from xdg-utils to
+query the database of standardized package information and ensure it
+return sensible values. It also need the location of an example file
+for xdg-mime to guess the format of.</p>

+<p>It is a simple way to ensure your users are not very surprised when
+they try to open one of your file formats in their file browser.</p>
