[Vala] Export vapi from libray

[Andy Lees <andrewl oz gmail com>]

Hi,

I would like to export an interface to some C structures from a vala
library that provides a number of other classes, etc.  If I include the
vapi and associated .h file in the library, it compiles fine, but does not
export the contents of the referenced vapi in the library vapi.

How would one go about including the vapi contents in the library interface?

Thanks for your attention.
