Apple's documentation reads, "One way to get to the tools is to log in to developer.apple.com and then use the search feature."
Fortunately, I found an easier way. Spoiler, you need to be a registered apple developer:
1) Go to https://developer.apple.com/
2) Go to the member center and log in
3) Click "SDK"
4) Find the "HTTP Live Streaming" link in the "Media" section
There will be a link on this page that will take you to the download page.
