Complete re-factoring of python module and command line tool
The program was split in two parts: 1. A python module, graph_tool.py, which encapsulates the graph manipulation under a Graph class. Now the following can be done: import graph_tool g1 = graph_tool.Graph() g2 = graph_tool.Graph() g1.load("foo.xml") g2.load("bar.xml") print g1.number_of_vertices(), g2.number_of_vertices() 2. A standalone command line tool, graph-tool, which imports graph_tool.py, and exposes the Graph methods as command line options. The whole command line engine was thus (once again) entirely rewritten. It is now Crack-Free™, and simply mirrors the methods of the Graph class as command line options, using, for this, the beauty of function decorators. It classifies now, I believe, as Pythonic™.
