+supports clean interruption, timeout, background tasks, and streaming STDIN /
+STDOUT / STDERR over binary or text connections.  The package also provides
+functions for evaluating expressions inside a temporary fork.  Such
+evaluations have no side effects on the main R process, and support reliable
+interrupts and timeouts.  This provides the basis for a sandboxing
+mechanism.")
