// XXX Why are these tests from checkout?
//
// Most of the self-test framework works by calling a meteor command and waiting
// for something to happen. Instead, the old tests call isolated functions (ex:
// bundler.bundle) and skip the (now, somewhat complicated) initialization
// process that would usually happen before these functions are called. We have
// managed to hack together some stuff to tide this over when running from
// checkout, but dealing with release overrides in not-checkout has mostly been
// a failure.
//
// It would be nice if these tests were to work from release, and maybe ekate
// will take another look at them later, but it is not worth that much more time
// before 0.9.0.
