Implementation cat unix tools using pure C programming language. (Just a draft tool for Donya OS)
- Tiny code
- Good performance
- Depends on glibc
- Support most features of unix cat tool
- Concatenation some files to one output
- Read from STDIN

-E, --show-ends display $ at end of each line
-n, --number number all output lines
-s, --squeeze-blank suppress repeated empty output lines
