Looks like a homebrew for windows.

Hi @treeder, I've created an installer package using the documentation from chocolatey and taken into consideration all rules. I've tested it and it successfully installed it on my windows machine. In order for me to push this to chocolatey, I have to create a key and push it from the console. But before I do, I wanted to check with you guys. I will gladly post a link to the repo for review purposes if required.

@martinpinto nice! Could you make a pull request here? Maybe put the files under /fn/chocolatey directory.

[treeder]

Or share the repo you have.

We'll probably have to do the initial upload though so we can own chocolatey package name if you don't mind?

I created a new PR #564 as requested. In order to create the package and test it a choco pack functions.nuspec command is required.
