> This repo seams not ment to be cloned onto a file system, which is case-insensitive.
> For example, (see below), this 2 files a different in the repo, but the file system
> can not have 'WordPress' and 'Wordpres's as different files or directories at the same
> time.
> This affects typically Mac OS and Windows users.

> There is actually some work going on right now to inform the user about this problem.
