APT_DEBUG_OPERATOR

APT_DEBUG_OPERATOR specifies the operators on which to start debuggers.

If APT_DEBUG_OPERATOR isd not set, no debuggers are started. If APT_DEBUG_OPERATOR is set to an operator number, as determined from the output of APT_DUMP_SCORE, debuggers are started for that single operator. If APT_DEBUG_OPERATOR is set to -1, debuggers are started for all operators.
