Subject: installation of BastionLedger-2.0.7 on Zope-2.8.5

Hello,
 	Thanks for your work to develop Bastion Ledger, and the other 
software you've released!  I'm investigating Bastion Ledger for 
integration with my information currency software, available at 
http://infoeng.sf.net.
 	I am trying to to get Bastion Ledger 2.0.7 installed on a Zope 
2.8.5 instance (which also has Plone 2.1.1 installed).  When I untar 
BastionLedger-2.0.7.tar.gz into my Zope instance, creating the 
<zope-instance-dir>/Products/BastionLedger directory, I don't see the 
BastionLedger product anywhere in the Zope management interface.
 	Do I need to do anything other than untar'ing the BastionLedger 
distribution in order to get Zope to recognize it?
 	Thanks in advance for your help!

 	Patrick
