Inline source map with closure compiler?

I am trying to debug a js file compiled with Closure Compiler with the corresponding source file (problem: the associated source file of the file does not show up in Chrome / firefox).

Is there a way with Closure Compiler to put the 'inline' source map into the compiled js file (instead of creating a separate map source file)?

If not, is it possible to modify the compiled js file to replace the reference to the original map with the content of the source map?
