4.1 Building a libscribbu program

Let us write a small C++ program using libscribbu to clean-up Amazon.com Song IDs. When downloading .mp3s from Amazon.com, their ID3v2 tags contain non-compliant comment frames (in that they have no description). They also try to cram it into the comment field in the ID3v1 tag, even though it’s generally too small to contain the entire string. We will call this program az-tags.
