Whats the difference between a Newt application and an NTK package?
Since Newt 3.0, there is no difference (as far as I can tell) between a Newt and a NTK-generated package. Both reside in a special area known as package memory. When you open your application, the package uses some dynamic memory — also known as frame heap — for run-time state (the “view”); however, much of the application (the “template”) remains in read-only package memory. Although NewtPack does not save font or store parts currently, it does save applications, books, autoparts and multipart packages. During development, Newt creates an application entirely in dynamic memory, except for references to built-in (ROM) objects. During the save process, Newt copies the application into package memory.
