 <p>
 This example shows how to construct a bidirectional map with
 <code>multi_index_container</code>. By a <i>bidirectional map</i> we mean
-a container of elements of <code>std::pair&lt;const FromType,const ToType></code>
-such that no two elements exists with the same <code>first</code>
-<i>or</i> <code>second</code> value (<code>std::map</code> only
-guarantees uniqueness of the first member). Fast lookup is provided
+a container of <code>(const FromType,const ToType)</code> pairs
+such that no two elements exists with the same first
+<i>or</i> second component (<code>std::map</code> only
+guarantees uniqueness of the first component). Fast lookup is provided
 for both keys. The program features a tiny Spanish-English
 dictionary with online query of words in both languages.
