+<H2>Introduction</H2>
+<P>
+          <CODE> pair&lt;class T&gt; </CODE> is a template class that provides arithmetic
+          and comparison operations on ordered pairs of elements of
+          type T. Class T must  implement arithmetic and comparison
+          operators.
+<P>
+          All operations are element-wise, including multiplication,
+          division and comparisons. Using these definitions, sets
+          of pairs are not well ordered in the mathematical sense. That
+          is, it is possible that for pairs p and q both p &lt; q and
+          p &gt; q could be false.
+<P>
+          Pairs of integers are quite useful for recording and
+          manipulating screen coordinates.
+<P>
+<BR>
+
+<H2>     Constructors </H2>
+
+          There are two constructors, one which takes two arguments of
+          type T, and sets the elements of the pair appropriately. The
+          other constructor takes no arguments, and initializes the
+          elements to zero.
