Boost was begun by members of the C++ standards committee Library Working Group to provide free peer-reviewed portable libraries to the C++ community. An additional objective is to establish "existing practice" and provide reference implementations so that the Boost libraries are suitable for eventual standardization. Indeed, the explicit intent is to propose many of these libraries for inclusion in the C++ Standard Library. The Boost Graph Library, formerly known as the Generic Graph Component Library (GGCL), is a collection of graph algorithms and data structures created in the generic programming style of the Standard Template Library (STL).
Yaacfi is an authentication, authorization, and access control filter for J2EE Web applications. This filter loosely emulates J2EE servlet container role based security with some extensions, and allows to easily implement login procedures for much more complicated user interaction schemes than the standard container-based security form login procedure. These schemas are required to provide cookie login, openid login, explicit login, etc. The filter is completely compatible with Struts.
