	Zope is not running (it can't!). If I run 'python checkds.py", I get:

ERROR: Run this tool under snapshot.py

	Looking at the code for checkds.py, it expects the enviromental 
variable 'SNAPSHOT_VERSION' to be set, or it will throw the above 
error. So it doesn't look like this script can be run outside of 
snapshot.py - or am I missing something?

	When I run under snapshot.py using the command you gave above, I still 
get the following:

failed to open /usr/zopestorage/config/snapshot.conf
SnapshotError: directory is not a snapshot

	So as it stands now, I have to run under snapshot, and it won't do 
that unless I have a snapshot.conf

	Since I had a disk crash, no, it was not a very clean shutdown.

	OK, maybe this should be obvious, but I have a few questions about 
this:

a) is the :5080 something specific to DirectoryStorage, or is that the 
port you typically run Zope on?
b) if it is your Zope port, how is this supposed to work if Zope can't 
run?
c) You list a relative path for your 'access' file, but what is it 
relative to?
d) How are the username and password formatted in that file?
e) is the password plain text or encrypted (using what)?
