<｜begin▁of▁sentence｜>### Instruction:
As a criminal psychologist, you often work with law enforcement agencies to analyze criminal behavior and motivations. Today, you have been provided with a GML file named 'crime_network.gml' containing data about criminal relationships and interactions within a specific criminal network. You need to use igraph's command line interface to extract a summary of the network properties directly in Python code, allowing you to gain insights into the structure and dynamics of this criminal network.
### Response:
from igraph import Graph
import igraph as ig
import sys

# Mock command line arguments
sys.argv = ['igraph', 'graph.gml', '--summary']

# Call the main function as if igraph was called from the command line
ig.main()
