Translation: «embeddable»

[Åsmund Skjæveland <aasmunds ulrik uio no>]

I'm trying to translate Nautilus. I'm stuck on, amongst others, this
string:

#: components/adapter/Nautilus_ComponentAdapterFactory_std.server.in.in.h:3
"Factory for objects that wrap ordinary Bonobo Controls or Embeddables to"
"look like Nautilus Views"

What is an "Embeddable" in this context? A brief explanation of the
concept, and, if possible, an example, would be very helpful.
