+--extract-scan can now find any file type, not just streaming video. By default
+it looks for video and audio; pass --scan-ext=iso,zip,mkv,flac (any extensions,
+any type) to scan for those instead, which also works on a plain directory
+listing. When a page has more than one matching file, flux opens a multi-select
+so you choose which ones go into the generated config.

 When you are happy with it, run the `flux --save-config <id>` line it suggests to
 install it active. Use `-o FILE` to write straight to a path instead.
