Mascot is a style checker for Objective Caml sources. It checks for overloading of built-in elements, useless constructs, deeply nested constructs, 'open' statements, magic numbers, complex conditions, presence of comments, spelling, empty interfaces and the number of exported elements, coupling, Halstead, and McCabe metrics, matching of regular expressions, and spaces, tabulation, headers, and file/line lengths. It supports CheckStyle, CSV, HTML, JDepend, bare text, and XML outputs, and supports plugins for custom checks and outputs.
