"ccbuild is a C++ source scanning build utility for code distributed over directories. Like a dynamic Makefile, ccbuild finds all programs in the current directory (containing "int main") and builds them. For this, it reads the C++ sources and looks at all local and global includes. All C++ source files in the same directories of the local includes are considered objects for the main program. The global includes lead to extra compiler arguments using a configuration file. Next to running g++ it can create simple Makefiles, A-A-P files, and graph dependencies using DOT (Graphviz) graphs."

The code should be an example of how to parse a file.
