[Zodb-checkins] CVS: Packages/ZEO - start.py:1.17

[Jim Fulton]

Update of /cvs-repository/Packages/ZEO
In directory korak:/tmp/cvs-serv12718

Modified Files:
	start.py 
Log Message:

      - It is no longer necessary to symbolically link cPickle or
        ZServer. ZServer is no longer necessary at all.

      - A Zope-style INSTANCE_HOME and var directory are no longer 
        needed.

      - If ZServer *is* available, the medusa monitor server can be
        used in the storage server.

      - An option, -d, was added to facilitate generation of a
        detailed debug log while running in the background.
