+This regular expression benchmark measures the time taken to match e-mails,
+URIs, and IP addresses in an input text. It is written in Rust and can be
+re-compiled using the `Dockerfile` (see [`build.sh`]).
+
+It is significantly adapted from the [regex-benchmark] project, which is [MIT]
+licensed. The [`default.input`] text is a concatenation of [Learn X in Y
+minutes] which is published under the [Creative Commons Attribution-ShareAlike
