/**
 * Knows how to serialize and deserialize the booter configuration.
 * 

 * The internal serialization format is through a properties file. The long-term goal of this
 * class is not to expose this implementation information to its clients. This still leaks somewhat,
 * and there are some cases where properties are being accessed as "Properties" instead of
 * more representative domain objects.
