[Zope] CallProfiler and Zope 2.7

[Brian Sullivan]

Does anybody know if CallProfiler 1.4
(http://zope.org/Members/richard/CallProfiler) is compatible with Zope 2.7?

I see various references to a call profiler included in 2.7 ( though I can't
find any evidence of it) -- is there something already there? If not can I
use CallProfiler 1.4? ( an attempt to include in the Products directory of
my instance seems to make Zope fail to start up so I am guessing that it
doesn't work or I misunderstand how to use it)
