饮羽公路测设（glcs） 由20多个公路测量、设计、试验和施工组织设计等小软件组成。如《中桩大地坐标》可以计算不等长缓和曲线的中桩和边桩的大地坐标；《缓和曲线反算》可以根据切线长、外距长或缓和曲线长求半径等；《卵型曲线精解》可以求精确的卵型曲线的参数；《混凝土配合比》可以快速进行混凝土配合比的设计。其他还有直线、曲线拟合，规划求解，网络图计算等等。所有各小软件计算的结果统一反映在主界面上，并在主界面中编辑、修改。并-Drink plume Highway Survey and Design (g

PTypes (C++ Portable Types Library) is a simple alternative to the STL that includes multithreading and networking. It defines dynamic strings, variants, character sets, lists and other basic data types along with portable thread and synchronization
