Developing graph analysis programs in python.

I needed nothing but the following libraries to make graph analysis programs (from file to file) in python.

1. CVS file IO module (http://docs.python.org/lib/module-csv.html)

2. Option parser (http://docs.python.org/lib/module-optparse.html)

3. SQLite3 (http://docs.python.org/lib/module-sqlite3.html) - a lite embedded DB engine

4. networkx (https://networkx.lanl.gov/)

Maybe you will do, too.
