Coffee, anybody with VS2013?

Coffee is perceived as an elegant programming language that compiles a script file with extension .coffee to a  Javascipt file (.js).  Bing it and you can find lot more references.

The Microsoft Visual Studio 2013 Exprees for Web seems to include access to a new item with the extension .Coffee as shown here.

However it is not supported on Microsoft Visual Studio 2013 Exprees for Web. It is supposed to work with extensions such as Web Essentials 2013 (free) which can be downloaded from here:
http://visualstudiogallery.msdn.microsoft.com/56633663-6799-41d7-9df7-0f2a504ca361

or using the Mindscape Web Workbench from here ( a free and not so free version):
http://visualstudiogallery.msdn.microsoft.com/2b96d16a-c986-4501-8f97-8008f9db141a

However, you cannot add these extensions to Microsoft Visual Studio 2013 Exprees for Web.
I failed to install although I tried both. The last few lines of the installation log is reproduced here,

I might have missed something, let me know if you succeeded.

Well, I have only the express edition, I go and get my coffee from somewhere else. Of course not, from Starbucks, coffee is way too much roasted for my taste.
