+    BrowserID Authentication for web2py

+    
+    thanks and credits to the web2py community
+    
+    This custom authenticator allows web2py to authenticate using browserid (https://browserid.org/)
+    BrowserID is a project by Mozilla Labs (http://mozillalabs.com/)
+    to Know how browserid works please visit http://identity.mozilla.com/post/7616727542/introducing-browserid-a-better-way-to-sign-in
+    
+    bottom line BrowserID provides a free, secure, de-centralized, easy to use(for users and developers) login solution.
+    You can use any email id as your login id. Browserid just verifys the email id and lets you login with that id.
