+/// <h1>PortAudioCpp - A Native C++ Binding of PortAudio V19</h1>\r
+/// <h2>PortAudio</h2>\r
+/// <p>\r
+/// PortAudio is a portable and mature C API for accessing audio hardware. It offers both callback-based and blocking \r
+/// style input and output, deals with sample data format conversions, dithering and much more. There are a large number \r
+/// of implementations available for various platforms including Windows MME, Windows DirectX, Windows and MacOS (Classic) \r
+/// ASIO, MacOS Classic SoundManager, MacOS X CoreAudio, OSS (Linux), Linux ALSA, JACK (MacOS X and Linux) and SGI Irix \r
+/// AL. Note that, currently not all of these implementations are equally complete or up-to-date (as PortAudio V19 is \r
+/// still in development). Because PortAudio has a C API, it can easily be called from a variety of other programming \r
+/// languages.\r
+/// </p>\r
+/// <h2>PortAudioCpp</h2>\r
+/// <p>\r
+/// Although, it is possible to use PortAudio's C API from within a C++ program, this is usually a little awkward \r
+/// as procedural and object-oriented paradigms need to be mixed. PortAudioCpp aims to resolve this by encapsulating \r
+/// PortAudio's C API to form an equivalent object-oriented C++ API. It provides a more natural integration of PortAudio \r
+/// into C++ programs as well as a more structured interface. PortAudio's concepts were preserved as much as possible and \r
+/// no additional features were added except for some `convenience methods'.\r
+/// </p>\r
+/// <p>\r
+/// PortAudioCpp's main features are:\r
+/// <ul>\r
+/// <li>Structured object model.</li>\r
+/// <li>C++ exception handling instead of C-style error return codes.</li>\r
+/// <li>Handling of callbacks using free functions (C and C++), static functions, member functions or instances of classes \r
+/// derived from a given interface.</li>\r
+/// <li>STL compliant iterators to host APIs and devices.</li>\r
+/// <li>Some additional convenience functions to more easily set up and use PortAudio.</li>\r
+/// </ul>\r
+/// </p>\r
+/// <p>\r
+/// PortAudioCpp requires a recent version of the PortAudio V19 source code. This can be obtained from CVS or as a snapshot \r
+/// from the website. The examples also require the ASIO 2 SDK which can be obtained from the Steinberg website. Alternatively, the \r
+/// examples can easily be modified to compile without needing ASIO.\r
+/// </p>\r
+/// <p>\r
+/// Supported platforms:\r
+/// <ul>\r
+/// <li>Microsoft Visual C++ 6.0, 7.0 (.NET 2002) and 7.1 (.NET 2003).</li>\r
+/// <li>GNU G++ 2.95 and G++ 3.3.</li>\r
+/// </ul>\r
+/// Other platforms should be easily supported as PortAudioCpp is platform-independent and (reasonably) C++ standard compliant.\r
+/// </p>\r
+/// <p>\r
+/// This documentation mainly provides information specific to PortAudioCpp. For a more complete explaination of all of the \r
+/// concepts used, please consult the PortAudio documentation.\r
+/// </p>\r
+/// <p>\r
+/// PortAudioCpp was developed by Merlijn Blaauw with many great suggestions and help from Ross Bencina. Ludwig Schwardt provided \r
+/// GNU/Linux build files and checked G++ compatibility. PortAudioCpp may be used under the same licensing, conditions and \r
+/// warranty as PortAudio. See <a href="http://www.portaudio.com/license.html">the PortAudio license</a> for more details.\r
