Hi,
There's actually a redesign of it and some not-so-practical features, such as operator overloading, are taken out.
Please see
here
Though there is no example or documents on it at the moment. The design is better than what I did before, though it's still quite experimental and the code also uses some cleanup. In this framework, scrapers can be inherited and you don't necessarily need to create a scraper from scratch for any new projects.
If you have questions or suggestions, welcome to shoot me an email, which is a better way to contact me.
Thanks :-)
