+// This is a bit of a funky one: it's from a [Babel plugin], but is exported for
+// Ember applications as the module `"htmlbars-inline-precompile"`. It acts
+// like a tagged string from the perspective of consumers, but is actually an
+// AST transformation which generates a function as its output. That function in
+// turn [generates a string or array of strings][output] to use with the Ember
+// testing helper `this.render()`.
