如何將樣板註釋或許可添加到使用Rails 3.1 Asset Pipeline編譯的JavaScript文件的頂部？

Question

我正在使用Asset Pipeline來構建一些JavaScript，這些JavaScript將被移交給許多第三方開發人員。我想在生成的（也可能是混淆的）輸出文件的頂部放置警告註釋，但不清楚如何使用鏈接/ coffeescript組合來實現此目的。

# This is a manifest file that'll be compiled into including all the files listed below. 
# Add new JavaScript/Coffee code in separate files in this directory and they'll automatically 
# be included in the compiled file accessible from http://example.com/assets/application.js 
# It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the 
# the compiled file. 
### 
    The following code was compiled from source by MF. 
    Please do not edit this JavaScript directly. 
#### 
#= require util/extensions 
#= require util/date_manipulation 
#= require util/format 
#= require points_data 
#= require graphics/canvas_graphics 
#= require graphics/explorer_canvas_graphics 
#= require renderer 

我得到這個結果如下：

(function() { 
    /* 
    The following code was compiled from source by MF. 
    Please do not edit this JavaScript directly. 
    */ 
}).call(this); 

我想是這樣的（或者相近）：

/* 
    The following code was compiled from source by MF. 
    Please do not edit this JavaScript directly. 
    */ 
(function() { 
    // ******** my compiled code from all those required files! ******* 
}).call(this); 

How'm'I會得到這個工作？

最簡單的方法是在編譯後向文件添加註釋。

的默認壓縮爲Rails - Uglifier - 有：保持文件的第一個註釋行，所以你可能用它來留在評論（和所有其他版權）著作權選項

config.assets.js_compressor = Uglifier.new(:copyright => true)

。
