<p>I am starting to get serious into C++ development. To that end, I want to learn more about what C++ libraries that are actually used in the real world. The only two well known production quality libraries that I know of is <code>boost</code> and <code>stl</code>. Is there any other C++ library that is well suited and tested for real world application? A light wrapper to some existing C library does not count. </p>

<p>Limited one per entry, and library specific to C++. Also give a short description to the library. </p>
