title: Android L battery historian.par tool missing
body: <p>Since Google made the updated SDK for Android L available on their website. I have been trying to test the new battery historian feature. The Google API overview <a href="http://developer.android.com/preview/api-overview.html" rel="noreferrer">website</a> claims that the tool is available under sdk/tools. Unfortunately even after ensuring that I have updated the SDK completely I am unable to find the tool anywhere. Does anyone know how I can access this tool?</p>
