--- Comment #5 from T.C. Hollingsworth tchollingsworth@gmail.com --- It's a dependency for running the test suite, which I'm not running right now due to a host of missing dependencies.
I didn't bother pruning devDependencies since nothing cares about them and we're not installing this package.json, but if you'd prefer I can '%nodejs_fixdep --dev -r' the testsuite-related ones we're skipping for now.
