These libraries started to be developed in the context of the Google SoC 2006. I want to thank Google for this amazing boost to the open source community and to Boost mentors to trusting in my proposal in the first place.

First, I want to thank my SoC mentor, Joaquin, for his friendship during this project. He not only helped me go through the process of creating this library, he did his best so we could have a great time doing it. Also, Boost.Bimap and Boost.MRU would not exist if Boost.MultiIndex, Joaquin master piece, did not exist. Thanks a lot! Special acknowledgments to the developers of the boost libraries that I have used.

I want to thank the open source developers that wrote the tools I used during this projects. The libraries are coded using Blade, a full open source development environment composed in my opinion of the best tools for software building. The list name is infinite, so I give a general huge thanks here.

Thanks to my family that helped me in persuing my goals. Special thanks to my brother Agustin, future famous novelist (at this time he is 19 years), that patiently read every word of this docs and while correcting them, barking at me for my bad English writing. I have learnt a lot of his sermons. I want to thank my dog, Mafalda, too for barking all day from my window and being such a good company.
