Coursera - lectures saving

Do you know Coursera? It's greatest online educational center.
A lot of courses in different areas and they all are FREE! My current course is ML (machine learning) :)
On the course you have a lot of resources (video, lectures). But when course is finished after several months video will be removed.

I've made python script course-ROBO-era - automate saving Coursera lectures locally - you can use it also - for FREE.
This script will save all available resources to "destination"  dir.

usage:

python course-robo-era.py --destination D:/study/coursera/ml --email [coursera email] --password [coursera password] --course-url https://class.coursera.org/ml-2012-002/lecture/index

Hope it will be useful for you :)
