This package provides a pluggable and stackable authentication system based on ideas and concepts from the Unix-PAM module. New authentication methods can be specified simply via a new LoginModule and chained together with the existing ones.

Note that the current implementation of this package is not complete, that is, not compatible with desktop implementations of the Java programming language. It contains only what was needed to make the compiler happy, that is, classes required by other packages. @since Android 1.0
