Usage: dep.sh [OPTION]... DIRECTORY
Scan and visualize C/C++ source file dependencies.
Options:
-e show extern dependencies
-h show help
-o FILENAME specify the output png name, default is "dep.png"
For an example project, we can get the following output.
If specified with -e option, we will get more dependencies.
Don't use this tool for large project. The generation of picture output is slow. And the readablity is poor.
