Technically it isn't any different, but it's based on the template engine code and templates that make up the 'Yocto BSP Tools', which for various reasons (they create Yocto-compliant BSP layers, something not of interest to OpenEmbedded proper, and it probably doesn't make sense to clutter oe-core with a bunch of 'template data', etc) live in poky and not oe-core. As such, the new tool is named 'yocto-layer' to match the other existing Yocto BSP tools, 'yocto-bsp' and 'yocto-kernel'.
