-# This script generates a redirects file that Netlify's CDN
-# can use to forward visitor to the right content.
-#
-# You can read more details about this file in Netlify documentation:
-#
-#     https://www.netlify.com/docs/redirects/
-#
-# USAGE:
-#
-# Run this script with Ruby to generate the _redirects file in this repository.
-# It works with any Ruby version higher than 1.8.
-#
-#     ruby redirects.rb
-#
-# If you want to test a change without modifying the content of the current file,
-# you can print the output of the script setting the DEBUG environment variable
-# when you run the script:
-#
-#     DEBUG=1 ruby redirects.rb
-#
-# You can test if the content generated is correct in this playground:
-#
-#     https://play.netlify.com/redirects
-#
-# HOW TO ADD NEW RULES:
-#
-# This script is divided in two sections.
-#
-# The first section handles static redirects,
-# those that you know the old path and the new path and never change.
-#
-# If you want to add one of these redirects, add the rule to the `fixed_redirects` variable,
-# in a new line before the closing """. The format for basic 301 redirects is the following one,
-# check Netlify's documentation linked above for other rules:
-#
-# /OLD_PATH /NEW_PATH_OR_URL
-#
-# The second section handles redirects that change depending on the branch that's deployed
-# in the site. For instance, when you want to redirect a path to content in
-# the kubernetes main repository but the content is specific to a branch that
-# matches the deployed branch.
-#
-# If you want to add one of there redirects, add the old path to the `branch_redirects` list. For instance,
-# when you deploy the branch release-1.5 on Netlify, this script will generate the following redirects:
-#
-# /examples/* https://github.com/kubernetes/kubernetes/tree/release-1.5/examples/:splat
-# /cluster/* https://github.com/kubernetes/kubernetes/tree/release-1.5/cluster/:splat
-# /docs/devel/* https://github.com/kubernetes/kubernetes/tree/release-1.5/docs/devel/:splat
-# /docs/design/* https://github.com/kubernetes/kubernetes/tree/release-1.5/docs/design/:splat
