About the submission
====================

The Promotion Traits extend Boost.TypeTraits with templates that compute the type after promotion has been applied.

Example:

   // given
   template<typename T> struct some_algorithm;
   template<> struct some_algorithm<int> { [...] };
   // [...] more specializations

   // ,

   [...] some_algorithm< typename integral_promotion<T>::type > [...]
   // makes some_algorithm work for any type T that promotes to an integer
   // (that is enums and smaller integral types) without the need for 
   // additional specialization


Review questions
================

Please always explicitly state in your review, whether you think the library should be accepted into Boost.

You might want to comment on the following questions:

- What is your evaluation of the design?
- What is your evaluation of the implementation?
- What is your evaluation of the documentation?
- What is your evaluation of the potential usefulness of the library?
- Did you try to use the library?  With what compiler?  
 Did you have any problems?
- How much effort did you put into your evaluation? A glance? A 
 quick reading? In-depth study?
- Are you knowledgeable about the problem domain?
