+%  This small piece of code fixes the frame numbering in beamer when using
+%  an appendix such  that the slides of the appendix are not counted in the
+%  total framenumber of the main part of the document. The total
+%  framenumber counter is reset to 0 and starts counting again when
+%  entering the appendix.
+% 
+%  Usage: \usepackage{appendixnumberbeamer}
+%  and declare the appendix as usual using the \appendix command.

+% Redefine the \appendix command:

+%   - freezes the total framenumber for this first part of the document
