More and more I'm liking the original idea of warning the user that
#import will not work for them and not including the binary file.
However, I think I do still need to parse the attribute stuff (to
ignore) for no other reason than so that the parser doesn't barf on
the rest of the file.

We can always revisit at a later date if we decide we want to try to
be more constructive or creative.

Any objections?
