Extracting HTTP responses from HAR file to filesystem

Is there a tool that can extract documents that appear in HTTP responses and dump them to the filesystem, ideally using path and filenames from the original HTTP requests?

What do HAR files contain?

What is a HAR file? HAR is an abbreviation of 'HTTP Archive'. It is a file containing a log of trace information from within a browser session. It records web requests made by the browser to the website page including request and response headers, the body, and the time it takes to load the assets.

https://github.com/outersky/har-tools can extract the response bodies into filesystem hierarchy that reflects the path from HTTP request.
