    Filter skeleton:

    Simply copy this file to <your_filter_name>.c and
    rename all filter_skeleton tokens to <your_filter_name>. Replace
    the stupid name and address in the Copyright few lines below.
    To active your new filter you have to create a new section in
    filter_vecs and finally add complying statements to Makefile.
