through.

I did not understand it. What is autoloading feature in rails searches  
means? I have also doubts in  
Dependencies.explicitly\_unloadable\_constants These types of things very  
difficult to understand …Could you please tell where to get proper  
documentation and all(or any blogs)

Autoleading means that when Rails sees Foo it knows to go and load the  
foo.rb file. Dependencies.load\_paths controls where it will search for  
that file

This to do with reloading in development mode. In normal usage you  
would nearly never need to use this.
