They have heard this many, many times.  It's not a simple thing to do,
given the history of VEE.

VEE 3.2 obtained much better file load times by a major revision of the
source file format ... in earlier versions, an object's view and internals
were in in the same part of the source file, in 3.2 they are separated and
classed as groups.  It's not a question of not being able to recognize
certain objects ... actually, there are relatively few new objects in 3.2
over 3.12.

This is indeed a severe inconvenience -- I'm rewriting my VEE tutorial with
hyperlinked examples, and I have to do them all in 3.12 so customers can get
them to load ... it's a pain to rewrite them.  It would have been nice to
get a file-conversion utility but it appears that would have been *very*
difficult to do.
