It allows you to free your iTunes Music Store purchases from their DRM restrictions with no sound quality loss. These songs can then be played outside of the iTunes environment, even on operating systems not supported by iTunes. It works on Mac OS X, many unix(-ish) variants and on Windows.
The Mac OS X version includes a drag-'n'-drop graphical user interface (GUI). The other platforms have only a command-line interface (CLI) at this time. Prebuilt binaries are available for both Mac OS X and Windows, and the source code is available for all platforms.

"To this end, copyright assures authors the right to their original expression, but encourages others to build freely upon the ideas and information conveyed by a work. This result is neither unfair nor unfortunate. It is the means by which copyright advances the progress of science and art." -- US Supreme Court Justice Sandra Day O'Connor
Despite what Justice O'Connor has said, DRM exists. The purpose of DRM is to circumvent traditional copyright law. The result of DRM combined with laws that outlaw circumvention of DRM (such as the DMCA is that there is no longer protection for fair use.
