"""%(program)s -- create a ZEO instance.
Usage: %(program)s home [port]
Given an "instance home directory" <home> and some configuration
options (all of which have default values), create the following:
<home>/etc/zeo.conf -- ZEO config file
<home>/var/ -- Directory for data files: Data.fs etc.
<home>/log/ -- Directory for log files: zeo.log and zeoctl.log
<home>/bin/runzeo -- the zeo server runner
<home>/bin/zeoctl -- start/stop script (a shim for zeoctl.py)
The script will not overwrite existing files; instead, it will issue a
warning if an existing file is found that differs from the file that
would be written if it didn't exist.
