Installing Laravel 4, oneliner
downloading package or setup composer.json could become a hassle. instead, just go with this one line of command on terminal. make sure you already installed composer and put it in the system wide bin (eg. /usr/local/bin/).
$ composer create-project laravel/laravel
this command also work if you want to setup a new package on composer packagist repo. for example installing Slimframework
composer create-project slim/slim
