An class providing an I/O writer abstraction that allows generating
output that can be stored or passed on to system files, strings
allocated in memory (usually via <a href="raptor-section-stringbuffer.html#raptor-stringbuffer"><span class="type">raptor_stringbuffer</span></a>), system
file handles (<code class="literal">FILE*</code>) or to a user function.
