The simplest option might be to provide a "xyz.notebook" subpackage
which references the main library and installs the iocaml printers.

Another solution could be to define an ocamlfind predicate such as
"notebook" which will automatically add the printers from the META
file.

archive(notebook) += "xyz_iocaml_printers.cma"

For iocamljs the kernel would then need to be compiled with
"-predicates notebook" added to the ocamlfind build command.  For
bytecode iocaml you would need to add "Topfind.add_predicates [
"notebook" ];" to the init file.

I am not so sure this second solution will play all that nicely with
the likes of oasis though - to do it properly the tools will need to
be taught about the notebook predicate in the same way they handle the
toploop predicate currently.
