zombie-globbies/Gulpfile.js

A very quick fix for [**Zombie**](https://github.com/assaf/zombie) to permit to crawl correctly webpages with attributes on the html tag (eg: html lang="en").

const assert = require('assert');
const clean  = require('gulp-clean');

const gulp   = require('gulp');

      notify({
        title:    'Fail!',
        message:  error.toString()

    });
  gulp.src('src/**/*.coffee')
    .pipe(compile)

});


// gulp watch -> watch for changes and compile
gulp.task('watch', ['build'], function() {

// git tag uses the generated .changes file

});
