I think I'm going to try this (on the fly fragment creation), as it would
seem to address my greatest issue which is merging all the package/versions
among all the different "classpath" jars I want to export. By simply
isolating each set of imports to it's own fragment it allows me to avoid
that complication.

Ok, that clears that up.

I'll try this. I just wanted to see if there was perchance a mechanism in
equinox that could help.

If all else fails, I may resort to bnd manifest calculation which is
another option (passing the "classpath" jars as though they were embedded).

Thank you
