+These benchmarks were ported out of the jetscii crate, specifically from
+[Dr-Emann's PR]. There were some irregularities in the benchmark results, so
+I thought it might be interesting to include it here.
+
+We add "real" variants of each benchmark as well using a small XML data set on
+mental health. The original benchmarks search a haystack consisting entirely of
+`a` repeated, with the last byte corresponding to one of the needle bytes. This
+is useful for measuring pure throughput, but less good for approximating real
+world performance. In this case, for at least `xml-delim3` and `xml-delim5`, it
+seems like an XML haystack would be better suited.
