1. SoftSTL, only read the basic library, WinSTL and Rangestl, all do not see (including all I didn't look at the back, superficial), see some usage and concept, the concept of Range I don't like, Sham is good, At least the Windows String is extracted from I love. 2. BOOST MPL (after reading Concept, no user manual), summary: 1) Use complex Template combination representation "Concept", 2) Template import function function, 3) Use the template to perform the credulgage function function. Feel: boring useless, it is better to see the way to see the matrix operation, although I believe it can also realize that, but it is too complicated, meaningless. 4. Boost String Algorithm LIB: Simple and practical, good. 5. BOOST TRIBOOL: Three-State (0, 1, Indetermined) type, usually two states (0, 1), interesting, perhaps in logic processing, and try to dig as much as possible
