This is the source for, a specification for "tagged netstrings".

It's a copy of the spec that was originally at, which has since disappeared. The original domain has been squatted on by some company that apparently specializes in such idiocy, so I opted to copy the latest version of the original spec I could find (thanks Internet Archive!) and publish it under a new domain.

As the site says, most of the text was written by Zed A. Shaw; I just fixed some mismatched tags, and added some CSS and the links to known implementations. Thanks to him for inventing the protocol in the first place and for this spec.
