Source Navigator NG 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 (commonly called
"symbols") which helps you discovering and mapping unknown source code
for enhancement or maintenance tasks.

source navigator NG is free software and released under the GPL
v2. It is based upon the old source navigator and strives to improve
usability and performance.
