Dynamically add version number to dest output files w/ grunt

I have a package.json file with our version number, such as:

{
    name: "myproject"
    version: "2.0"
}

My goal is to dynamically add the version number from the package.json file into the output files. For example, in the javascript I don't want to manually update the version number, but would like something similar to this to be generated after each grunt build:

/* My Project, v2.0 */
window.myProject = {
    version: "2.0"
};

Is there an easy way to do this in my Gruntfile.js configuration?
