shoe-horn a web page into a single html file
Make HTML more self-contained by in-lining:
For straightforward cases, this will take an HTML document which might have external dependencies and return an HTML document with no external dependencies - a single self-contained file that you could send as an email attachment, or show as a presentation without worrying about internet connectivity, for example.
Loaded as a module, selfcontain() takes an HTML string and base path or URL and is the main function to know. Command-line usage wraps the minor extension selfcontain_ref(), which takes a string specifying a file path or URL to fetch and process:
selfcontain test_in.html > test_out.html # or selfcontain https://raw.githubusercontent.com/ajschumacher/selfcontain/master/test_in.html > test_out.html
