在网上找了好久，ede的相关文档很少，最后在emacs 的info里找到了。
在emacs中打开帮助，找到ede项：
C-h i

ede
可找到如下帮助，在Extending EDE项里有所有的参考文档，包括工程件的编写格式等。
EDE
***
EDE is the Emacs Development Environment: an Emacs extension that
simplifies building and debugging programs in Emacs. It attempts to
emulate a typical IDE (Integrated Development Environment). EDE can
manage or create your makefiles and other building environment duties,
allowing you to concentrate on writing code rather than support files.
It aims to make it much easier for new programmers to learn and adopt
GNU ways of doing things.
This file describes EDE, the Emacs Development Environment.
