+/**
+ * Provides support for alternate implementations of the JShell execution
+ * engine.  The JShell core tracks and compiles Snippets then sends them
+ * (represented in a wrapper class) to the execution engine for loading,
+ * and in the case of executable Snippets, execution.  The JShell
+ * implementation includes a default execution engine (currently a remote
+ * process which is JDI controlled).  By implementing the
+ * {@link ExecutionControl} interface and installing it with
+ * {@link jdk.jshell.JShell.Builder#executionEngine(jdk.jshell.spi.ExecutionControl) }
+ * other execution engines can be used.
+ * <p>
+ * This is not a part of the JShell API.
