What's the `el-get` initial flow to install and configure packages?

[ghost]

Would anyone like to show me how the el-get is called after start Emacs and how and when it starts to install and configure the package which is managed with el-get-bundle?

I've been meaning to write an overview of the install and init flow with a view to simplifying/improving it. I just now posted something to https://github.com/dimitri/el-get/wiki/Dev-notes-on-package-install-and-initialization-procedures.

Unfortunately, the way el-get-bundle puts together the init files is fairly tricky and I don't really understand it. Probably only @tarao can explain it fully.
