# This is a script for the CGAL test suite. Such a script must obey
# the following rules:
#
# - the name of the script is cgal_test
# - for every target two one line messages are written to the file 'error.txt'
#     the first one indicates if the compilation was successful
#     the second one indicates if the execution was successful
#   if one of the two was not successful, the line should start with 'ERROR:'
# - running the script should not require any user interaction
# - the script should clean up object files and executables
