This is not a "library"! This is just a pile of code chunks. It is not like Steve Donovan's PenLight. It provides no guarantees for backward compatibility. But has general idea: do not repeat code. So there are many code chunks. They are relatively small and usually has links to another, absolutely necessary, code chunks. I'm using it as a resource base for my projects. I can automatically extract chunks that are used by code and pack them in distribution. So in distribution there are no dead code. You are free legally use them under GPLv3. 2017-05-05 One more, there is constant "in progress" state. I'm starting yet another experiment with directory structure and digging into implementing some interesting things. So structure is not final. It will never be final. This is like quantum world: observation makes changes. 2017-08-15
