30 <H2>Introduction</H2>
31 <P>
32 <CODE> pair&lt;class T&gt; </CODE> is a template class that provides arithmetic
33 and comparison operations on ordered pairs of elements of
34 type T. Class T must implement arithmetic and comparison
35 operators.
36 <P>
37 All operations are element-wise, including multiplication,
38 division and comparisons. Using these definitions, sets
39 of pairs are not well ordered in the mathematical sense. That
40 is, it is possible that for pairs p and q both p &lt; q and
41 p &gt; q could be false.
42 <P>
43 Pairs of integers are quite useful for recording and
44 manipulating screen coordinates.

48 <H2> Constructors </H2>
49
50 There are two constructors, one which takes two arguments of
51 type T, and sets the elements of the pair appropriately. The
52 other constructor takes no arguments, and initializes the
53 elements to zero.
