B<run>
Restart debugger and program via an I<exec()> call.
Hash reference variable $Devel::Trepan::Core::invoke_opts contains a
hash of options that were used to start the debugger. These are
consulted in figuring out how to restart.
=head2 See also:
L<C<show args>|Devel::Trepan::CmdProcessor::Command:Show::Args> for
the exact invocation that will be used.
