But dependency tracking is hard and all of these platforms only scratch the surface. For example, I've never seen a solution that detects C libraries used from other languages, let alone the dependencies of these libraries. Then there are build-time dependencies which are hard to detect. Here's an example of a complex dependency chain:
redmine -> ruby-commonmarker -> libcmark -> re2c
Wake me up if someone offers a solution that detects chains like that.
