UltraCard (not Vapor!)
UltraCard v.s. HyperCard stacks.
Apple has not released (and I am a Mac developer too) the format for
HyperCard stacks. They don't want other systems to be able to read the format.
Maybe in the future we will attempt to reverse engineer it but for now we just
want to get our product out.
The doc will include some Hyper:Ultra comparisons and hints for
transporting stacks.
