While holding the configuration file in XML has some
self-referential elegance, I'm not sure how we solve the
bootstrapping problem of parsing an XML file in order to
discover what parser to use!
Better here, I think, to use the simple keyword=value format
defined by java:
parser.AElfred=com.microstar.xml.SAXDriver
parser.xp=com.jclark.xml.sax.Driver
preferred.parser=xp
