30  * <code>MuleClasspathConfigurationBuilder</code> can be used to configure a
31  * MuleManager based on the configuration files on the classpath. the default config
32  * resource name is <b>mule-config.xml</b> but this can be overrided by passing a
33  * config resourse name or a list of resource names (comma separated) to the
34  * configure method.
35  *
36  * @deprecated The functionality of this configuration builder (loading resources
37  * from the classpath) is now available in the standard
38  * MuleXmlConfigurationBuilder. If you are using this builder, please
39  * verify whether your configuration will work with
40  * org.mule.config.builders.MuleXmlConfigurationBuilder as this class is
41  * deprecated and is soon to be removed.
