	<div style="margin-left:  0px;">
		The <b>BOOST_PP_ITERATION_PARAMS_<i>x</i></b> macro is a user-defined <i>named external argument</i> used by <b>BOOST_PP_ITERATE</b>.&nbsp;
		It denotes the lower bound, upper bound, and the filename of a <i>file-iteration</i>.&nbsp;It can optionally denote flags associated with a <i>file-iteration</i> as well.
	</div>
	<h4>Usage</h4>
		<div class="code">
			#define <b>BOOST_PP_ITERATION_PARAMS_<i>x</i></b> (<i>c</i>, (<i>start</i>, <i>finish</i>, <i>filename</i> [, <i>flags</i>]))
		</div>
	<h4>Arguments</h4>
		<dl>
			<dt>x</dt>
			<dd>
				The iteration depth of the next <i>file-iteration</i>.&nbsp;
				This value <i>must</i> be the current iteration depth + <i>1</i>.
			</dd>
			<dt>c</dt>
			<dd>
				The number of parameters.&nbsp;
				If <i>flags</i> is specified, this value must be <i>4</i>.&nbsp;
				Otherwise, it must be <i>3</i>.
			</dd>
			<dt>start</dt>
			<dd>
				The lower bound (inclusive) of a <i>file-iteration</i>.&nbsp;
				Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_ITERATION</b>.
			</dd>
			<dt>finish</dt>
			<dd>
				The upper bound (inclusive) of a <i>file-iteration</i>.&nbsp;
				Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_ITERATION</b>.
			</dd>
			<dt>filename</dt>
			<dd>
				A quoted or angle-bracketed filename to used as the target of a <i>file-iteration</i>.
			</dd>
			<dt>[flags]</dt>
			<dd>
				The flags associated with this <i>file-iteration</i> used to discriminate between different <i>file-iterations</i> in the same file.
			</dd>
		</dl>
	<h4>Remarks</h4>
		<div>
			Note that there is a whitespace character after the macro identifier.
		</div>
		<div>
			This macro is must be defined as an <i>array</i> of arguments in one of the two formats above (with or without <i>flags</i>).
			It is the primary method of passing arguments to <b>BOOST_PP_ITERATE</b>.&nbsp;
			Both <i>start</i> and <i>finish</i> are <i>evaluated parameters</i>, which implies that simple arithmetic can be used.
		</div>
		<div>
			This macro is automatically undefined for reuse by a call to <b>BOOST_PP_ITERATE</b>.
		</div>
