Related brief introduction:

Composer is a dependency management tool above PHP5.3. It allows you to declare the code base on which the project depends, and it will install them for you in your project. Composer is not a package manager. Yes, it involves "packages" and "libraries", but it is managed on a project-by-project basis and installed in a directory of your project (such as vendor). By default, it does not install anything globally. Therefore, this is just a dependency management.
