Macker is an architectural rule-checking utility for Java. It's meant to model the architectural ideals programmers always dream up for their projects, and then break. It is not a lint checker--it operates on a more global, more logical level, focusing on class dependencies rather than source code formatting. Macker has no default set of rules; it's flexible, and writing a rules file is part of the development process for each unique project. You can tailor a rules file to suit a specific project's structure, or write some general "good practice" rules for your code. Macker typically runs as an Ant task, but can also be invoked with a shell script.
