Document how to add many-to-manys using this tool?

[GoogleCodeExporter]

I'm attempting to add a Contact to an Account, and I'm sure it's super obvious 
how to do it, but I didn't see anything in the documentation about it, and I'm 
failing at the various things I've tried. Can you put an example in for how to 
add one record to another record where many-to-many relationships exist?

Thanks.
