Newbie - importing URLs

I have a txt file of thousands of urls that I want to scrape the same data from.

My simple question is, how to I get sss to read from this file,

scrape the data (I can create the scrapable file and extractor patterns),

write the scraped info to a txt file or database,

Then start all over again with the next URL on the list,

repeat until at the bottom of the list.

Regards,
Joseph.

PS - I am using the free version of sss
