This command defines how the debugger handles signals.
The debugger can detect any occurrence of a signal in your program. You can define in advance how the debugger should handle each kind of signal. Normally, the debugger is set up to let some signals like SIGUSR1 be silently passed to the debuggee, but to stop your program immediately whenever an error signal happens. This command changes these settings.
