Description

The greeter from the Frontier contract tutorial, stripped to its point: a string given at construction and a greet function that returns it. The tutorial's version inherits a mortal base so the creator can recover the balance and remove the contract; this deployment drops that inheritance entirely, so the greeting cannot be changed and the contract cannot be killed. It has stood unchanged since.
