+this library provides on average the fastest builder of strict bytestrings.
+Practical benchmarks have proven it to be highly performant as well. The
+encoders from the postgresql-binary library have shown a stable performance
+improvement by factors of up to 10 after the migration from the standard builder
+to bytestring-strict-builder.")
