+"Launch a command interpreter session. Commands are read from standard input or
+from the input handle specified for the debugger object. Output/errors are
+similarly redirected to standard output/error or the configured handles.
+
+ at param[in] auto_handle_events If true, automatically handle resulting events.
+ at param[in] spawn_thread If true, start a new thread for IO handling.
+ at param[in] options Parameter collection of type SBCommandInterpreterRunOptions.
+ at param[in] num_errors Initial error counter.
+ at param[in] quit_requested Initial quit request flag.
+ at param[in] stopped_for_crash Initial crash flag.
+
+ at return
+A tuple with the number of errors encountered by the interpreter, a boolean
+indicating whether quitting the interpreter was requested and another boolean
+set to True in case of a crash.
+
+Example:
+
+# Start an interactive lldb session from a script (with a valid debugger object
+# created beforehand):
+n_errors, quit_requested, has_crashed = debugger.RunCommandInterpreter(True,
+    False, lldb.SBCommandInterpreterRunOptions(), 0, False, False)") RunCommandInterpreter;
