Recently, a very large [python library](https://github.com/networkx/networkx) had an issue opened about creating the `requirements.txt` for it. It was not very easy for people involved to write down an exhaustive list. Hence, I thought of writing something which could do the job. See [here](http://apps.himanshumishra.in/depends/). It simply crawls every module and digs out the imports from places and generates a dictionary of builtin and non-builtin modules. I wonder what more can be done with these data of dependencies if we have them in large number? I am very eager to discuss it here.
