Where is the vcl-bin subdirectory?

Abstract: Where is the vcl-bin subdirectory?

  Q:Looking at the installation directory I can't find any vcl-bin sub directory, but the source code of my web page refers to it

A:When the VCL folder is on a higher level than the running application, the framework uses vcl-bin as an alias to the folder the VCL resides, so you will need to add that alias to your webserver.
