=head2 Synopsis:

B<info signals>

B<info signals> I<signal1> [I<signal2> ..]

In the first form a list of the existing signals and actions are shown.

In the second form, list just the given signals and their definitions
are shown.

Signals can be either their signal name or number. The case is not
significant when giving a signal name. A signal name C<SIG> or
not. For a signal number, you can preface the number with C<+> or
C<->, but both are ignored. A negative number is the same as its
corresponding positive number.

=head2 See also:

L<C<handle>|Devel::Trepan::CmdProcessor::Command::Handle> for descriptions of the settable fields shown.
