Two months ago Barend Gehrels announced on the OSGeo Discuss list ongoing Open Source project called Generic Geometry Library, GGL in short.
The Generic Geometry Library provides a generic implementation of geometry algorithms, working with geometry types provided by the library itself as well as user-defined types. The library is implemented in C++ programming language with extensive use of elements of metaprogramming like class (type) templates, static polymorphism and compile-time execution. Consequently, GGL is built upon two of the greatest pieces of C++ code ever written by humanity: C++ Standard Library and Boost C++ Libraries.
In my opinion, this project is valuable and have potential which may interest many of us, FOSS4G users and developers. The OSGeo Foundation agreed to host this mailing list ggl@lists.osgeo.org dedicated to discussions development and use of the Generic Geometry Library.
