Sniffer

A JS library for sniffing out information about pages, such as which JS libraries are used, what CMS the site runs on, what analytics packages it uses, and more. It is intended to be used in bookmarklets or injected JS widgets that need to gather information about the host page and it's component parts.

Where it can, Sniffer will return a string with more information (such as a version number) for each test; otherwise it will return boolean true or false.

Please see the main site at http://allmarkedup.github.com/sniffer/ for more information and usage instructions.
