embedding sample

Hello,

I can't find any usabe sample of how currently embedding should work.

on Windows winEmbed just print some funny text into console and exit.
nothing for linux.

Do we have some samples (for any platform, better - for linux) of how
to embed Gecko in versions 8.0.1 or 9.0.1 (latest mozilla codebase)?

Or maybe some open-source projects exists which use recent Gecko
embedding?

thanks.
