Currently, people are managing dependencies, such as JavaScript libraries, manually. This sucks, and we want to change it. Bower is a package manager for the web. Bower lets you easily install assets such as images, CSS and JavaScript, and manages dependencies for you.

In a nutshell, Bower is a generic tool which will resolve dependencies and lock packages down to a version. It runs over Git, and is package-agnostic. A package may contain JavaScript, CSS, images, etc., and doesn’t rely on any particular transport (AMD, CommonJS, etc.).

Bower then makes available a simple programmatic API which exposes the package dependency model, so that existing build tools (like Sprockets, LoadBuilder, curls.js, Ender, etc.) can consume it and build files accordingly.
