The Pharo By Example book says to open it through the Tools submenu - but I don't see this in Pharo 3.0
Is there another way?
You cannot use Seaside Control Panel because it was made in OmniBrowser which is not included in Pharo 2.0+
Instead, you can use:
ZnZincServerAdaptor startOn: 7070.
and
ZnZincServerAdaptor stop.
