RouteMap, a new open source client/server-side JavaScript URL Mapping Library

One thing to make clear: simply using #! does not make your app crawlable. Your server-side app needs to also handle URLs that contain _escaped_fragment_, per Google's specification:<p><a href="http://code.google.com/web/ajaxcrawling/docs/getting-started.html" rel="nofollow">http://code.google.com/web/ajaxcrawling/docs/getting-started...</a>

Would it be possible to use pushState as the main mechanism on the client, and use a #! as a fallback? You would end up with two different possible URLs, but if the same library handles the calls then it would be fairly straightforward to move from one to the other.

Not to be overly pedantic, but a piece of core functionality like this seems like it would really need some basic automated tests, even if they were just running the API through it's paces.<p>The thorough documentation is awesome though!
