+which is then compiled into low-level machine code by the Julia compiler.  The
+package is designed to generate very efficient code to scan large text data,
+which is often much faster than handcrafted code.  @code{Automa.jl} can insert
+arbitrary Julia code that will be executed in state transitions.  This makes
+it possible, for example, to extract substrings that match a part of a regular
+expression.")
