Ruby recursively require all files in directory

#recursively require all files in directory (and subdirectories)
Dir["#{File.dirname(__FILE__)}/squat/**/*.rb"].each {|file| require file }

#recursively require all files in directory but skip paths that match a pattern
Dir["#{File.dirname(__FILE__)}/squat/**/*.rb"].each do |file|
  require file unless file =~ /\/model\//
end
