Thanks for the contribution!

Thanks

I think we may still want to use relative paths (from what is said in the doc comment) on windows in the symlink, but current version is already an improvement to make it work better in windows.

Approving and will merge in a few days

Looks good!

Agree on that. Absolute paths have caused quite some trouble when I introduced them (and only for a short period of time)
