What is this notation: "//@" in Javascript?

The minified jQuery library file contains this comment at the top:

/*! jQuery v2.0.2 | (c) 2005, 2013 jQuery Foundation, Inc. | jquery.org/license
//@ sourceMappingURL=jquery-2.0.2.min.map
*/

Chrome is making requests for that file which isn't being found.

What is the meaning of the line starting with //@? Is it only used for source maps? Googling three non-alpha-numeric characters isn't yielding many results.

Yes, it's for source maps.

"This enables developer tools to map calls back to their location in original source files."
