1935 * - we parse the command line ourselves, without modifying

1938 * result of a GTK command line (i.e. not detailed errors in
1939 * particular options of ours) we store the error message
1940 * and terminate parsing.
1941 * - if we got enough out of the command line to know it
1942 * specifies a non-X mode of operation, we either display
1943 * the stored error and return failure, or if there is no
1944 * stored error we do the non-X operation and return
1946 * - otherwise, we go straight to gtk_init().
