+The delivery of a signal.
+
+With no arguments, this catchpoint will catch any signal that is not
+used internally by @value{GDBN}, specifically, all signals except
+@samp{SIGTRAP} and @samp{SIGINT}.
+
+With the argument @samp{all}, all signals, including those used by
+@value{GDBN}, will be caught. This argument cannot be used with other
+signal names.
+
+Otherwise, the arguments are a list of signal names as given to
+@code{handle} (@pxref{Signals}). Only signals specified in this list
+will be caught.
+
+One reason that @code{catch signal} can be more useful than
+@code{handle} is that you can attach commands and conditions to the
+catchpoint.
+
+When a signal is caught by a catchpoint, the signal's @code{stop} and
+@code{print} settings, as specified by @code{handle}, are ignored.
+However, whether the signal is still delivered to the inferior depends
+on the @code{pass} setting; this can be changed in the catchpoint's
+commands.
