+/**
+* InternetHeaders is a utility class that manages RFC822 style
+* headers. Given an RFC822 format message stream, it reads lines
+* until the blank line that indicates end of header. The input stream
+* is positioned at the start of the body. The lines are stored
+* within the object and can be extracted as either Strings or
+* {@link Header} objects. <p>
+* <p/>
+* This class is mostly intended for service providers. MimeMessage
+* and MimeBody use this class for holding their headers. <p>
+* <p/>
+* <hr> <strong>A note on RFC822 and MIME headers</strong><p>
+* <p/>
+* RFC822 and MIME header fields <strong>must</strong> contain only
+* US-ASCII characters. If a header contains non US-ASCII characters,
+* it must be encoded as per the rules in RFC 2047. The MimeUtility
+* class provided in this package can be used to to achieve this.
+* Callers of the <code>setHeader</code>, <code>addHeader</code>, and
+* <code>addHeaderLine</code> methods are responsible for enforcing
+* the MIME requirements for the specified headers.  In addition, these
+* header fields must be folded (wrapped) before being sent if they
+* exceed the line length limitation for the transport (1000 bytes for
+* SMTP).  Received headers may have been folded.  The application is
+* responsible for folding and unfolding headers as appropriate. <p>
