usage="""Test speed of a ZODB storage

Options:

    -d file    The data file to use as input.
               The default is this script.

    -n n       The number of repititions

    -s module  A module that defines a 'Storage'
               attribute, which is an open storage.
               If not specified, a FileStorage will ne
               used.

    -z         Test compressing data

    -D         Run in debug mode

    -L         Test loads as well as stores by minimizing
               the cache after eachrun
