var main = function(async,path){

    var removeFile = function(callback){
        var path = path.resolve(__dirname);

        async.waterfall(work,(err) => {

            callback(null);
        });
    };

    return {
        removeFile: removeFile
    }
};

module.exports = main;

/* index.js */
const diContainer = require('di-containerx')();

diContainer.register('path', require('path'));
diContainer.register('async', require('async'));
diContainer.factory('main', require('./lib/main'));

const main = diContainer.get('main');
main.removeFile((err) => {
