module Sprockets::Paths

def prepend_path(path)

Paths at the end of the `Array` have the least priority.

Prepend a `path` to the `paths` list.
def prepend_path(path)
  self.config = hash_reassoc(config, :paths) do |paths|
    path = File.expand_path(path, config[:root]).freeze
    paths.unshift(path)
  end
