It is the ancient product initialization -- used by the first
products: e.g. DTML Document and Method and ZSQL Method.

It was superceeded by product local constructors -- for the obvious
reason to avoid name clashes.

It is -- if you know and use the implementation details
of Zope's security subsystem:

   To protect a method "m" with permission "p",
   you assign "PermissionRole(p)" to "m__roles__".

Not that a maintainer (without the same detailed knowledge
about the security subsystem) would understand such
a "method" -- unless you had put in an explaining comment...
