/**
 * GAppInfo and GAppLaunchContext are used for describing and launching
 * applications installed on the system.
 *
 * As of GLib 2.20, URIs will always be converted to POSIX paths
 * (using g_file_get_path()) when using g_app_info_launch() even if
 * the application requested an URI and not a POSIX path. For example
 * for an desktop-file based application with Exec key totem
 * %U and a single URI,
 * sftp://foo/file.avi, then
 * /home/user/.gvfs/sftp on foo/file.avi will be
 * passed. This will only work if a set of suitable GIO extensions
 * (such as gvfs 2.26 compiled with FUSE support), is available and
 * operational; if this is not the case, the URI will be passed
 * unmodified to the application. Some URIs, such as
 * mailto:, of course cannot be mapped to a POSIX
 * path (in gvfs there's no FUSE mount for it); such URIs will be
 * passed unmodified to the application.
 *
 * Specifically for gvfs 2.26 and later, the POSIX URI will be mapped
 * back to the GIO URI in the GFile constructors (since gvfs
 * implements the GVfs extension point). As such, if the application
 * needs to examine the URI, it needs to use g_file_get_uri() or
 * similar on GFile. In other words, an application cannot assume
 * that the URI passed to e.g. g_file_new_for_commandline_arg() is
 * equal to the result of g_file_get_uri(). The following snippet
 * illustrates this:
 *
 * GFile *f;
 * char *uri;
 *
 * file = g_file_new_for_commandline_arg (uri_from_commandline);
 *
 * uri = g_file_get_uri (file);
 * strcmp (uri, uri_from_commandline) == 0; // FALSE
 * g_free (uri);
 *
 * if (g_file_has_uri_scheme (file, "cdda"))
 *  {
	 *  // do something special with uri
 *  }
 * g_object_unref (file);
 *
 * This code will work when both cdda://sr0/Track
 * 1.wav and /home/user/.gvfs/cdda on sr0/Track
 * 1.wav is passed to the application. It should be noted
 * that it's generally not safe for applications to rely on the format
 * of a particular URIs. Different launcher applications (e.g. file
 * managers) may have different ideas of what a given URI means.
