+SystemRequirements: V8 engine version 6+ is needed for modern JS and WASM support. On 
+    Debian / Ubuntu install either libv8-dev or libnode-dev, on Fedora use v8-devel. 
+    The readme has instructions for installing backports on Ubuntu Xenial and Bionic. 
+    It is still possible to build this package against the legacy libv8 version 3.14
+    branch, but these engines only support traditional (ES5) JavaScript.
