Starting DUB 0.9.24 (http://forum.dlang.org/post/qgxuxkspzjwxagypnsaw@forum.dlang.org) a DUB description file in SDLang is supported. This should also be supported by the plugin as it seems to replace old definitions files in JSON quite soon (because it is easier to write and maintain as well allows comments).
