title: How can I run a build from another gulpfile?
body: <p>As part of my build process, I need to run a gulp build on a submodule from another project. I know I can use "require('path/to/other/gulpfile.js')", but it doesn't seem like gulp does anything to handle task name collisions. Both gulpfiles have a "build" task.</p>
  
  <p>Is there a way to rename an already-defined gulp task at runtime?</p>
