## Features
- [x] Parse Mach-O directly, no Symbols option required in Strip style of Build Settings, __no depends on otool__.
- [x] Unused selectors.
- [x] Unsued classes.
- [x] Unused protocols.
- [x] Duplicate selectors.
- [x] All classes.
- [x] Selector/Classes/Protocols sort by library, and selector size, if Linkmap file provided.
- [x] Fast, a 460.6M binary and a 134.3M linkmap file costs 1.62s(3.7 GHz 6-Core Intel Core i5;40 GB 2667 MHz DDR4).
