Hi,

I'm trying to get the implementation of the "required" protocol as 
described by Nathanael Shärli and Andrew P. Black. It seems the most 
recent is in TraitsOmniBrowser but when I try to load it from monticello 
(http://www.squeaksource.com/TraitsOmniBrowser), I get a dependency error:

This package depends on the following classes:
   OBBrowserTest

Where can I find this class or where can I get the implementation of the 
"required" protocol ?

Thank you
