Sat Nov 13 22:30:29 GMT 1999 Tony Gale  <gale@gtk.org>

        * docs/gtkfaq.sgml: threads example from Erik Mouw.
        New question on GtkLabel background colors.

        * docs/gtk_tut.sgml:
          - Correct the example code callback
            function definitions.
          - Update the gtkdial example code, from Frans van Schaik.
          - Update setselection.c to current API.

        * examples/Makefile examples/*/*.c: Update to code
        listed in tutorial.
