:Description:
 Join is an asynchronous, message based C++ concurrency
 library based on join calculus. It is applicable both to
 multi-threaded applications and to the orchestration of asynchronous,
 event-based applications. It follows Comega's design and
 implementation and builds with Boost facilities. It provides a high
 level concurrency API with asynchronous methods, synchronous methods,
 and chords which are "join-patterns" defining the synchronization,
 asynchrony, and concurrency.
Pimpl

:Download: https://github.com/boost-vault/Miscellaneous/blob/master/Pimpl.zip
:Description:
 The Pimpl idiom is a simple yet robust technique to minimize
 coupling via the separation of interface and implementation and then
 implementation hiding.  This library provides a convenient yet
 flexible and generic deployment technique for the Pimpl idiom.  It's
 seemingly complete and broadly applicable, yet minimal, simple and
 pleasant to use.
Sorting

:Author: Steven Ross
:Review Manager: Needed
:Download: https://github.com/boost-vault/Sorting
:Description:
 A grouping of 3 templated hybrid radix/comparison-based sorting
 algorithms that provide superior worst-case and average-case
 performance to std::sort: integer_sort, which sorts fixed-size data
 types that support a rightshift (default of >>) and a comparison
 (default of <) operator.   float_sort, which sorts standard
 floating-point numbers by safely casting them to integers.
 string_sort, which sorts variable-length data types, and is optimized
 for 8-bit character strings.
 All 3 algorithms have O(n(k/s + s)) runtime where k is the number of
 bits in the data type and s is a constant, and limited memory overhead
 (in the kB for realistic inputs).   In testing, integer_sort varies
 from 35% faster to 2X as fast as std::sort, depending on processor,
 compiler optimizations, and data distribution.   float_sort is roughly
 70% faster than std::sort.   string_sort is roughly 2X
 as fast as std::sort.
Quaternions, Vectors, Matrices

:Description:
 QVM defines a set of generic functions and operator overloads for
 working with quaternions, vectors and matrices of static size. The
 library also defines vector and matrix data types, however it allows
 users to introduce their own types by specializing the q_traits,
 v_traits and m_traits templates.
Variadic Macro Data

 handling cyclic collections.
Singularity
-----------
:Author: Ben Robinson
:Review Manager: Needed
:Download: https://github.com/cppmaven/Singularity
:Description: The Singularity Design Pattern allows you to restrict
  any class to a single instance. Unlike the infamous Singleton,
  Singularity gives you direct control over the lifetime of the object,
  does not require you to grant global access to the object, nor does it
  limit you to the default constructor for that object.
Extended Complex Numbers
------------------------
:Author: Matthieu Schaller
:Review Manager: Needed
:Download: http://code.google.com/p/cpp-imaginary-numbers/
:Description:
 The library is an extension of the std::complex class addressing two issues:
 1.  The standard does not guaranty the behaviour of the complex class if 
     instantiated with types other than float/double/long double.
 2.  Some calculation where pure imaginary numbers (i.e. multiples of
     sqrt(-1)) appear are unnecessarily slowed down due to the lack of
     support for these numbers.  The code I submit contains two
     interleaved classes boost::complex and boost::imaginary which can
     be instantiated with any type T provided T overloads the usual
     arithmetic operators and some basic (real) mathematical functions
     depending on which complex function will be used.  It is thus an
     extended version of Thorsten Ottosen's n1869 proposal
     (http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2005/n1869.html)
Metaparse
---------
:Author: Abel Sinkovics
:Review Manager: Needed
:Download: http://abel.web.elte.hu/metaparse/metaparse.zip
:Description:
 Metaparse is a library for constructing parsers parsing at
 compile-time based on template metaprogramming. The parsers built with
 the library take boost::mpl::strings as input and can produce
 - types
 - objects (types with public static members)
 - callable C++ functions (types with public static method)
 - template metafunction classes
 as output (based on the input being parsed).
 On compilers supporting constexpr the library provides the following
 syntactic sugar for writing the input of the parsers:
 BOOST_STRING("this is a string")
 The library can be used for implementing DSLs in C++, including DSLs
 making C++ template metaprogramming easier (see examples).

:Description:
 The proposed library [stl_ext_adv] offers augmented array based B+ trees 
 and STL containers that support the interfaces of the C++03 sequences 
 and associative containers. The library offers a number of extensions 
 and performance improvements that are not available in 
 C++03 and C++11 standard containers. 
Countertree

:Description:
 This library is an implementation of a binary red-black counter tree. This
 tree have an additional counter in each leaf. This permit the access to the
 elements by the position, like in a vector. It is a random access container
 with random access iterators. 
 COUNTERTREE
 This kind of trees have an additional counter in each leaf. This
 permit the access to the elements by the position, like in a
 vector. It is a random access container with random access iterators.
 With unordered information we have a vector with the same speed
 inserting and deleting in any position (O(log N)).  With ordered
 information, we have the classes set, multiset, map and multimap, with
 identical interface than the STL classes, with the plus of access to
 the elements by position, like in a vector. The iterators are random
 access , and you can subtract them.
 SUBALLOCATOR
 The suballocator is a layer between the allocator and the data
 structures, compatible with any allocator with the STL definition. The
 suballocator replace to the allocator in the allocation of equal size
 elements. It provides speed, return the unused memory and decrease the
 memory used by the program and improve the cache performance due to
 the data locality improvement ( 30% of improvement of speed respect
 the std::allocator with GCC 4.7)

  * terminate processes
Asynchronous File I/O

:Author: Niall Douglas and Paul Kirth
:Review Manager: Needed
:Download: https://github.com/BoostGSoC/boost.afio/archive/boost-peer-review.tar.gz
:Description: 
  Boost.AFIO is a linear scalable, batch, chainable,
  asynchronous closure execution engine with an almost wait free
  implementation extending Boost.ASIO and Boost.Thread specialised as a
  portable asynchronous file i/o implementation library. Implementation
  of this first version has been kept as simple as possible (~ 1000
  active LOC) at the cost of some performance, though with a good
  compiler you can expect 25-50% of the performance of using raw
  Boost.ASIO.

:Description:
 Application provides an application environment, or start point
 to any people that want a basic infrastructure to build an system
 application on Windows or Unix Variants (e.g. Linux, MacOS).
 
 Application uses behaviours modeled using 'aspects' concept
 proposed by 'Vicente J. Botet Escriba', that allow easy extension and
 customization of library components. The application modes uses these
 components internally to achieve the user desirable behaviours.
 Application provide many useful ready-to-use features, e.g:
 * Run application as Windows Service;
 * Run application as UNIX/POSIX Daemon;
 * Plugin extension system;
 * Process(executable) Single instance Instantiation support;
 * Application SIGNAL/Callbacks customization;
 * Windows Service Setup feature;
 * And many others.
