Fully standard platform-independent C++, only one C++ header with about 300 lines of code, and yet good enough to be useful for practical work.
Designed for those places where you don't want to integrate large, incomprehensible code bases you don't understand.
I find the title a bit confusing. I first thought this would simplify and/or compress code (minify).
