SLint is a tool, included in the Refactoring Browser package, which tests your code against a set of quality rules. It helps to detect bugs, and helps to improve maintainability and understandability of the code.
One can write extensions to SLint, as suggests the page GM SLint Extensions
In the latest RB release, Lint is available as an option in the Worlds open menu. In older releases SLint is opened by evaluating: LintDialog open. You then see a window allowing you to select various tests to run against a set of classes.
An alternative is to install the BrowseUnit package, which offers you to run SLint on a class with a single mouse click!
