Source Navigator NG is based upon Red Hat's Source Navigator. Source Navigator is a source code analysis tool. With it, you can edit your source code, display relationships between classes and functions and members, and display call trees. You can navigate your source code and easily get to declarations or implementations of functions, variables, and macros, which helps you discover and map unknown source code for enhancement or maintenance tasks. Source Navigator NG tries to improve usability and performance.Changes: This release added a new feature for selectively removing nodes (refers to, referred from) from the xrefpane.
