Within his Bachelor thesis about search space limitation (details follow soon), Mark Kubacki established Apache Maven (amongst others) in the qKAI application framework:
Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project’s build, reporting and documentation from a central piece of information. (http://maven.apache.org/)
With Maven we got a nice project documentation now – available under http://docs.qkai.org. Especially the API section is work in progress and will be enhanced by and by.
