[Zope] Where can I found "hot_plug" function of zpi.zope ?

[KLEIN Stéphane]

Hi,

I search the definition of "hot_plug" function.

I look it at "CMFQuickInstallerTool/QuickInstallerTool.py" file. The 
line code is that :

from zpi.zope import not_installed, hot_plug

I not found hot_plug function in my Product/ directory and not in Zope 
source. Where can I found it ?

Thanks for your help
