```ruby
require 'pp'
require_relative 'docparser'

$classes = parse_any_path 'src'

def prefix lines

			klass[:mixins].each do |mixin|
				out.push prefix describe mixin
			end
		end
	end
	out.select{|a| !a.empty? }.join "\n"

$classes.sort_by!{|klass|
	# sort by "type" first (widget/layout/element/etc.), then by name
	klass[:name].split(/(?=Layout|Widget|Element|Dialog|Tool|Theme)/).reverse
