Version:          1.0.9.0 (26 April 2005)

CGAL Versions:    3.0 and 3.1

Supported Compilers & Platforms:

Purpose:
     This package implements the visibility complex data structure for planar
     scenes.

Description:

      Distributed with this package are the following things:

                        postscript format
        doc_html/    -- directory containing the package documentation in
                        Html format
	demo/        -- two small graphical (LEDA) demos illustrating the package. 
			see demo/README for more details.
        cep_test     -- shell script for running the test suite
        include/     -- directory containing the Visibility_complex header files
        test_suite/  -- directory containing the test suite source code,
                        input and output files
 
      This package can be used to compute the visibility graph or visibility
      complex of planar scenes. These scenes can consist in pairwise
      non-intersecting points, segments, circles or polygons.
      The package can also be used to compute the shortest path between two
      points in such scenes.

Changes:
      1.0    initial release
      1.0.1  fix for gcc-3.x compilers
      1.0.2  fix in the documentation
             added a small word about shortest path in the user manual
      1.0.3  This version is usable with CGAL-3.0.
             Perhaps does it still work with CGAL-2.2 but it is not sure.
      1.0.9.0 Version for CGAL-3.1 and gcc >= 3.4.
