+entrypoints required to use Vulkan without linking to vulkan-1.dll or
+statically linking Vulkan loader. Additionally, volk simplifies the use of
+Vulkan extensions by automatically loading all associated
+entrypoints. Finally, volk enables loading Vulkan entrypoints directly from
+the driver which can increase performance by skipping loader dispatch
+overhead.")
