- * <h2>SYNOPSIS</h2>
- *<blockquote>
- *     Object used to store messages in the ASX framework.
- *</blockquote>
- *
- * <h2>DESCRIPTION</h2>
- *<blockquote>
- *     <tt>MessageBlock</tt> is modeled after the message data structures
- *     used in System V STREAMS. A <tt>MessageBlock</tt> is composed of
- *     one or more <tt>MessageBlock</tt>s that are linked together by <em>PREV</em>
- *     and <em>NEXT</em> pointers. In addition, a <tt>MessageBlock</tt> may also be
- *     linked to a chain of other <tt>MessageBlock</tt>s. This structure
- *     enables efficient manipulation of arbitrarily-large messages
- *     <em>without</em> incurring memory copying overhead.
- *</blockquote>
