Clone all forks in a GitHub repository's network.

clone_github_network.rb

#!/usr/bin/env ruby

require 'json'
require 'open-uri'
require 'fileutils'

def clone_repo(repo)
	puts repo['full_name']
	owner, path = repo['full_name'].split('/')
	FileUtils.mkdir_p(owner)
	unless File.directory?(repo['full_name'])
		`git clone "#{repo['clone_url']}" "#{repo['full_name']}"`
	end
end

github_api = "https://api.github.com/repos"
master = File.join(ARGV[0],ARGV[1])
FileUtils.mkdir_p(master)
Dir.chdir(master)
clone_repo(JSON.parse(open("#{github_api}/#{ARGV[0]}/#{ARGV[1]}").read))

forks = JSON.parse(open("#{github_api}/#{ARGV[0]}/#{ARGV[1]}/forks").read)
forks.each do |fork|
	clone_repo(fork)
end

This probably doesn't work for cloning all forks of a gist, does it?
