If you take a look here: http://twistedmatrix.com/trac/browser/trunk/twisted you’ll find an organized, comprehensive, and very well tested suite of many protocols of the internet, as well as helper code to write and deploy very sophisticated network applications. I wouldn’t confuse bloat with comprehensiveness. It’s well … Read more
