+      A fork of Intel's Hyperscan, modified to run on more platforms. Currently
+      ARM NEON/ASIMD is 100% functional, and Power VSX are in development.
+      ARM SVE2 will be implemented when hardware becomes accessible to the
+      developers. More platforms will follow in the future, on demand/request.
+
+      Vectorscan will follow Intel's API and internal algorithms where possible,
+      but will not hesitate to make code changes where it is thought of giving
+      better performance or better portability. In addition, the code will be
+      gradually simplified and made more uniform and all architecture specific
+      code will be abstracted away.
