Above codes allow me to create a directory.
1 line expresses that this file is ruby process.
2 line is Main thread starting sign, 8 line is end sign.
4 line checks to exists or not.
7 line real make directory.

This is great but leads to a race condition. I would recommend wrapping the mkdir in a try/catch block
begin
Dir::mkdir(directory_name)
