1)Cross platform(gcc in linux and msys+mingw in window$)

2)Ability to append a file to existing archive

3)Ability to remove a file from existing archive

4)Format of archive is'nt important but for speed reason it should not be compressed

5)If it support compressing for my future developing is cool
