I've updated the documentation at <URL:
The "Hello World" example has been corrected to work with version 0.2,
and no longer requires you to write any Objective-C code. Actually, it
no longer requires you to write any Perl code, either... it's all done
visually, using Interface Builder.
Two new HowTos have been added, that illustrate how to respond to GUI
events, and how to manipulate GUI widgets from within your Perl code.
Never put off until tomorrow what you can do today. There might be a law
against it by that time.
