There is a lot of XML here, so let's start at the top. Beginning with the normal Spring configuration
file imports and the inclusion of your normal launch-context.xml file, this file contains 10 uniquely
configured beans (not including nested beans of the actual step or job). Table 8-1 walks through each of
the beans configured in this file.
