FlWin project started in 2016, in 2017, the name is changed 
to flos. In 2018, the project name is reset to FlWin. The last 
version of FlWin/Flos is FlWin 5.x, and tested in the start of 
2019, which is never been released.
         I think the flos 2.0 is the best release of that project, 
so the idea is base on the flos 2.0 build.</property>
