3. Compiling Script
大部分的開源軟體專案都是提供泛用的設定,但根
據不同的使用環境及產品,將會有對應重建應用的
安裝資訊 (build instruction) 。原始的開源專案網
站並未揭露,那麼這些安裝資訊、重建應用的
build instruction ,是否也會被列入是 GPL 合規
的必要文件之一?
Source Codes
The source code for a work means the preferred
form of the work for making modifications to it.
Installation Information, Compiling Scripts and
so on...
