composer Introduction:
Composer is a dependency management tool for PHP5.3 and above. It allows you to declare the code libraries your project depends on and it will install them for you in your project. Composer is not a package manager. Yes, it involves "packages" and "libraries", but it's managed on a per-project basis, with installations in some directory within your project (e.g. vendor). By default it won't install anything globally. So this is just a dependency management.
