TutFind :Fun with python

I dont like googling for tutorials. Thats why I made TutFind- a download utility just for web learners. TutFind makes use of Google to find possible pages where we will get free stuff and download it. This multi threaded application simultaneously search hundreds of pages by traversing the web in a limited depth. Python's powerful urllib and  regular-expression form the core of this application.

Here I am searching for PDFs of python tutorial. I gave the search keywords "python tutorial" and specified that I want PDF documents by entering ".pdf" as file extension. Also the target folder ids set to "dest". We will get a collection of PDF tutorials at /home/dest (sorry about the poor GUI facilities provided). On search, we got a list of available PDF(Here they are only four since the depth and breadth of search is set very small).
