Include Trees show you who depends on a given C or C++ header (.h) file (include file dependency) as well as what header files a given section of code depends on. In the example below, the top is a graphical IncludeBy Tree, which documents who uses a given include file (and who includes them, and so on). The bottom left is an Include Tree, which shows what a given include file depends on. The bottom right shows the Information Browser showing all information available for an include file. Includes and Include-By are partially drilled down. Each diagram can be copied/pasted into other applications, printed, or saved as a JPG, PNG, Postscript or BMP file for inclusion in other documentation. These trees (and any other graphic Understand) draws can also be automatically dumped by a PERL script.
