    use Devel::WrapExports;

    # The same thing, but ignore the specified packages and subs...
    use Devel::WrapExports
        exempt_pkgs => [ qw( Devel Carp CGI ) ],
        exempt_subs => [ qw( Nevermind::me ) ];

    # Use my own subs for tracing instead of the defaults...
    use Devel::WrapExports
        pre   => q{ sub { "custom pre-wrapper..."  } },
        post  => q{ sub { "custom post-wrapper..." } };

    # Run as script to list fully-qualified names of each symbol (sub or otherwise) in the top-level scope...
