So, I have updated my jam-integration branch, with a registration
function, and a set of exporters. At registration time, you give both
the name of the format (which is accessible from the command line
--format), and a list of extensions which can be auto-detected.

I also updated the test suite so that it tests exporting to a ZipFile. I
probably would also like to be able to throw a custom exception at
_loader time, which the front end could handle. Something like
"MissingDependency".

That could be used by any of the lazy loaders, in order to indicate what
you actually need in order to be able to use the functionality.

But for now, I think I'm happy with the way it is.
