/** \class cmCTestScriptHandler
 * \brief A class that handles ctest -S invocations
 *
 * CTest script is controlled using several variables that script has to
 * specify and some optional ones. Required ones are:
 *   CTEST_SOURCE_DIRECTORY - Source directory of the project
 *   CTEST_BINARY_DIRECTORY - Binary directory of the project
 *   CTEST_COMMAND          - Testing commands
 *
 * Optional variables are:
 *   CTEST_BACKUP_AND_RESTORE
 *   CTEST_CMAKE_COMMAND
 *   CTEST_CMAKE_OUTPUT_FILE_NAME
 *   CTEST_CONTINUOUS_DURATION
 *   CTEST_CONTINUOUS_MINIMUM_INTERVAL
 *   CTEST_CVS_CHECKOUT
 *   CTEST_CVS_COMMAND
 *   CTEST_DASHBOARD_ROOT
 *   CTEST_ENVIRONMENT
 *   CTEST_INITIAL_CACHE
 *   CTEST_START_WITH_EMPTY_BINARY_DIRECTORY
 *   CTEST_START_WITH_EMPTY_BINARY_DIRECTORY_ONCE
 *   
 * In addition the follwing variables can be used. The number can be 1-10.
 *   CTEST_EXTRA_UPDATES_1
 *   CTEST_EXTRA_UPDATES_2
 *   ...
 *   CTEST_EXTRA_UPDATES_10
 *
 * CTest script can use the following arguments CTest provides:
 *   CTEST_SCRIPT_ARG
 *   CTEST_SCRIPT_DIRECTORY
 *   CTEST_SCRIPT_NAME
