  - Replaced all use of 'zope.interface' with 'peak.interface' because   - Replaced all use of 'zope.interface' with 'protocols' package because
    the new 'peak.interface':     the 'protocols' package:

      where 'x' is an 'A', will be implemented as BC(AB(x)).       where 'x' is an 'A', will be implemented as BC(AB(x)).
   
      * Supports "open protocols" that allow you to "superclass" a protocol
        to create a subset protocol; objects that support the first protocol
        will automatically support the subset protocol.  For example, if one
        person defines a "dictionary" protocol, someone else can create a
        "read-only dictionary" protocol, and all objects supporting the
        "dictionary protocol" will be considered to implement the "read-only
        dictionary" protocol.
