You just wrote a cpp program that reads it config from a file named conf.ini.
As you don't want to bother adding all files manualy, you have decided to use .gitignore.

You need to create a .gitignore file that will:
- Ignore all files that end with a ~ (bakup files)
- Ignore every files in the out directory but conf.ini

In other words, once the .gitignore file written, the command `git add .` should only stage:
- .gitignore
- main.cpp
- out/conf.ini
