Daily exercise reptiles - climb PPT

Foreword

PPT network is really a treasure, ideal for novices to operate reptiles practice, not only at work learning to use ppt templates, you can also practice reptiles.

The site clearly directory structure, not do too much anti-climb, anti-hotlinking case there is only a part of the link, if the whole point was to climb there is a certain amount of work.
Based on this station, I would like to achieve the following objectives:
call link in Thunder Batch Download Station with Python, and while the file is renamed
today to grasp the idea that, behind have to take the time to realize my needs. Come to Oliver!
