"Node's module resolution allows you to replace your gulpfile.js file with a directory named gulpfile.js that contains an index.js file which is treated as a gulpfile.js. This directory could then contain your individual modules for tasks. If you are using a transpiler, name the folder and file accordingly."
This is supported by gulp. It would be nice if your plugin also supported it.
