Maintaining discipline of code in an evolving software project is known to be difficult. We present Minik, an automatic tool written in Java and for Java, that assists technical managers to enforce high and medium level design decisions on programmers. The tool supports hierarchical encapsulation of software components and helps to maintain order in dependencies between parts of the project's source code and to control calls to external libraries. Minik was created to support the development of Ocean GenRap Report Generator, a complex Java project of over 350KLOC, developed in Comarch Research Center. With time, it became an invaluable help for technical managers as well as for new programmers who could quickly learn the structure of the code base.Phase use the following format when citing this chapter:
