dtangler is a suite of tools to analyze dependencies. dtangler's primary features currently are:

• DSM GUI (Dependency Structure Matrix)
• DSM text-based output
• Command line dependency analyzer (primary targeted for use in automated builds)
• Support for reading dependency info from a text file
• Built in support for Java dependency analysis (jar/class folder, package, and class level)
• The user can write dependency rules and dtangler checks if the code follows the rules.
