Expose a version string
Provide a base scope for accessing singletons that I2P exposes.
Base class of I2P exceptions This was originally used to provide chained exceptions, but those were added to Exception in Java 1.4, so this class provides nothing extra at the moment.
Core I2P package, contains information about the I2P version and an entry point to access important elements.
With a few exceptions, this package and all others in i2p.jar are maintained as a stable API for use by apps, clients, and plugins.
