We have js libs on github

Our Jsfile (yeah like Gemfile :)) will looks like yaml file, or ruby dsl

I all js files should be compiled in to files: libs.js and application.js
application will be changed on every deploy, but libs will be changing only then you require new lib

rubygems-like server should store information about libs and compiled versions of then

In future it should handle with package.yml and mootools-forge like header comments to calculate and fetch dependences

Jsfile.rb

lib 'mootools' do
  repo 'http://github.com/mootools/mootools-core.git'
  tag  '1.2.4'
end

lib 'mootools-more' do
  repo 'http://github.com/mootools/mootools-more.git'
  tag  '1.2.4'
end

# or just
lib 'mootools', '1.2.4'
# this can be used only for libs registered on our server

# to build application.js
application do
  in 'public/javascripts' do
    use    'application.js', 'classes/*.js', 'views/*.js'
    ignore 'classes/*_spec.js'
  end
end

build do
  compress_with :jsmin, :gzip
  put_at        'public/javascripts'
  application   'all.js.gz'
  libs          'libs.js.gz'
end
