[Zope] Hotfix / 2.2.0 question

[Christopher J. Kucera]

Greetings, fellow Zopers!  A quick, non-urgent question for you all:

After recently upgrading to 2.2.0, I noticed that under Control
Panels/Products,
I still had an entry for the security Hotfix from oh, so long ago, despite
the fact that it's quite absent from my 2.2.0 Products directory.  I just
assumed it was safe to delete, so I did, but I'm wondering why it was there,
and if, indeed, I should have deleted it. :)

Thanks for your help,
CJ
