Currently only contains the limited "graph-includes" tool. . Graph-includes creates a graph of dependencies between source-files and/or groups of source-files, with an emphasis on getting readable and usable graphs even for large projects. . Usability of the dependency graphs are currently improved by: - customizable grouping of several source files into a single node - transitive reduction of the graph . It currently supports graphing the C/C++ #include relationship, using graphviz by default. Limited support is provided to draw 3D graphs using tulip.
