What is the Augeas plug-in?
The Augeas plug-in is an abstract plug-in that exists solely as an extension point for other plug-ins. The Augeas plug-in provides the Java JNI classes necessary for other dependent plug-ins to use to access the Augeas native library. For example, the OpenSSHD plug-in depends on the Augeas plug-in because it uses the Augeas library to access the OpenSSH daemon configuration.
