I write my build scripts in Frontier, I might be the last person in the world to do this.
Anyway I had to do a major rewrite of the build script for rss.chat, and got tired of the fact that Frontier doesn't have anything like console.log in JavaScript. So I wrote one.
The console is an outline of course, and there are two verbs, console.start and console.log. And they work very nicely. Each start creates a new top level headline with the time in it, and then the subsequent console.log's go in under the time.
Anyway you can download it here. You won't see anything on your screen but if you View Source you will see it's a fat page. Oh the humanity. ;-)
