Malu is created and working.
It is published at npmjs.com/package/malu, the latest release is 0.0.2. Owners of the package at npmjs.com are @dduvall and me.
Example code on how to use it is in Gerrit patch 256404. The patch used to work fine with Malu 0.0.2 but it is broken for the current version of Firefox (46). The fix is simple, Malu depends on selenium-webdriver ~2.47.0. Upgrading to the latest version of selenium-webdriver (2.53.2) fixes the problem. It has been a while since I have tried it, but the patch should work fine with the current version of Chrome.
