When I attempt to run my gulp-documentation task, it works fine on the file pointed to as the `src`, but won't recurse into any of my imported files. Here's the task in question: ``` gulp.task('docs', () => { return gulp.src('src/init.jsx') .pipe(documentation({format: 'md', filename: 'api.md'})) .pipe(gulp.dest('docs')) }) ``` and the command I use to run my gulp task: ``` NODE_PATH=$NODE_PATH:src NODE_ENV=development babel-node ./node_modules/.bin/gulp docs ```
