javascript - Browser & version in prototype library?

I am used to using Atlas. Recently i have started transitioning to jQuery and sometimes prototype. The project that i'm currently working on is using prototype.

In Prototype, is there an easy way to get the browser name and version? I've looked over the API documentation and can't seem to find it.

See Question&Answers more detail:os

As a completion to nertzy's answer you can add the ability for detecting IE versions using this:

Prototype.Browser.IE6 = Prototype.Browser.IE && parseInt(navigator.userAgent.substring(navigator.userAgent.indexOf("MSIE")+5)) == 6;
Prototype.Browser.IE7 = Prototype.Browser.IE && parseInt(navigator.userAgent.substring(navigator.userAgent.indexOf("MSIE")+5)) == 7;
Prototype.Browser.IE8 = Prototype.Browser.IE && !Prototype.Browser.IE6 && !Prototype.Browser.IE7;

On the other hand you have to detect user agent details on the server side, too. Anyways browser detection is a seriously flawed strategy for writing cross-browser scripts, that's just to be used when browser feature detection fails. It's pretty easy for a user to alter his/her user agent details.
