            Boost.Bimap is intuitive because it is based on the standard template
            library. New concepts are however presented to extend the standard maps
            to bidirectional maps. The first step is to gain a firm grasp of the
            bimap framework. The first section (Discovering
            the bimap framework) aims to explain this.

            Boost.Bimap offers much more than just a one-to-one ordered unique bidirectional
            map. It is possible to control the collection type of each side of the
            relationship that the bimap represents, giving one-to-many containers,
            hashed bidirectional containers and others that may be more suitable
            to the the task at hand. The second section (Controlling
            collection types) explains how to instantiate a bimap with different
            collection constraints.

            The section (The
            "collection of relations" type) explains how to create
            new types of bidirectional maps using custom collection types.

            In the section Differences
            with standard maps we will learn about the subtle differences
            between a bimap map view and a standard map.

            The section Useful
            functions provides information about functions of a bimap that
            are not found in the STL.
          
- 
            The types of a bimap can be tagged so that each side is accessible by
            something closer to the problem than left and right. This leads to more
            readable, self-documenting code. The fourth section (Bimaps
            with user defined names) shows how to use this feature.

            The bimap mapping framework allows to disable a view of a bimap, including
            the standard mapping containers as a particular case. The section Unconstrained Sets
            explains how they work.

            The section Additional
            information explains how to attach information to each relation
            of a bimap.

            The final section (Complete
            Instantiation Scheme) summarizes bimap instantiation and explains
            how change the allocator type to be used.
