CCS for Java
This is the Java implementation of CCS.
CCS is a language for config files, and libraries to read those files and configure applications. The documentation is currently quite poor, but the Java and C++ implementations are mature and have been used in production for many years.
There's a presentation about the language here, but it's a little sketchy without someone talking along with it. A syntax reference is here.
