Generating Javadocs for individual modules...

Currently I'm offered the option to generate javadocs for my whole project or just a single package. I'd like to be able to generate docs at the module level. Is there a way to do this?

Also, I'd like to be able to access the javadocs for dependent modules from within idea but I can't see how this is done. The only way to associate javadocs with a given module is to have the target module in the library path. Is it possible to do it if the module is only listed as a dependent module?

thanks for your help,
