# This is the test script for the CGAL-library.
#
# Usage:
#   run_testsuite                  for running the test suite in all subdirectories
#   run_testsuite <directory-list> for running the test suite in the listed
#                                  subdirectories
#
# To use this script you have to do two things:
#
# 1) enter the makefiles of the platforms that you want to test with (below)
# 2) set some additional compiler and or linker flags
