Boost Format library
  The format library provides a class for formatting arguments according
  to a format-string, as does printf, but with two major differences
  :
  
    - format sends the arguments to an internal stream, and so is entirely
    type-safe and naturally supports all user-defined types.
- The ellipsis (...) can not be used correctly in the strongly typed
    context of format, and thus the function call with arbitrary arguments is
    replaced by successive calls to an argument feeding
    operator%
  You can find more Details in :

- Sample programs
      
        - The program sample_formats.cpp demonstrates
        simple uses of format.
- sample_new_features.cpp
        illustrates the few formatting features that were added to printf's
        syntax such as simple positional directives, centered alignment, and
        'tabulations'.
- sample_advanced.cpp
        demonstrates uses of advanced features, like reusing, and modifying,
        format objects, etc..
- And sample_userType.cpp shows the
        behaviour of the format library on user-defined types.
