Gwtar: A static efficient single-file HTML format

Gwtar is a new polyglot HTML archival format which provides a single, self-contained, HTML file which still can be efficiently lazy-loaded by a web browser. This is done by a header’s JavaScript making HTTP range requests. It is used on Gwern.net to serve large HTML archives.
