     This Package allows the automatic detection of cracks and
     corresponding statistical analysis of crack quantities. The output
     of the crack detection program contains the pixels of crack
     clusters, the pixels of crack paths, and the start and end points
     of the crack paths. These quantities can be used for a detailed
     statistical analysis of crack growth.
