I am curious why all the \r added... @moT01 what do you say?

[gikf]

There are two factors to that:

• Git replaces line endings to \r\n locally on windows, by default. When committing git replaces line ending with just \n, so \r in the line endings doesn't make it into commits.
• CodeRoad cli generates tutorial.json using file with \r\n. Which is how \r\n make into the generated strings.

I guess it could be tried to force git using just \n line ending in the repository, with .gitattributes file having:

* text eol=lf

Thanks for clarifying that @gikf. I don't think they cause any problems, but do you think you can remove all those from this PR @srkds?
