Jentchina is the client library part of "The Birds Lake" framework. It is independent of any graphical toolkit. Its role is to create the filter trees, to maintain them, and to propose an API that enables the application of a filter the easiest way possible (while remaining independent of any GUI). The Birds Lake is a big framework for applying a filter on a document using a remote filter server.
Lioubliou is a library part of "The Birds Lake" project. It is used to write filter servers. Lioubliou takes cares of filter sessions, registers servers in local database, and abstracts network messages. It supports CORBA via ORBit, but the design of the library can support other communication media later. It also abstracts lsmlib.
