/**
 * <p>A signature file as defined in the <a
 * href="manifest.html">Manifest and Signature Format</a>. It has
 * essentially the same structure as a Manifest file in that it is a
 * set of RFC 822 headers (sections). The first section contains meta
 * data relevant to the entire file (i.e "Signature-Version:1.0") and
 * each subsequent section contains data relevant to specific entries:
 * entry sections.
 *
 * <p>Each entry section contains the name of an entry (which must
 * have a counterpart in the manifest). Like the manifest it contains
 * a hash, the hash of the manifest section corresponding to the
 * name. Since the manifest entry contains the hash of the data, this
 * is equivalent to a signature of the data, plus the attributes of
 * the manifest entry.
 *
 * <p>This signature file format deal with PKCS7 encoded DSA signature
 * block. It should be straightforward to extent to support other
 * algorithms.
