I’m having a global variable that is placed in development.rb. How can I  
change the value of that variable from within the code and store it back  
to the config file?

I’ve been told in the IRC channel that it is not practical to store it  
in the \*.rb file, and that a better approach would be storing it in my  
custom config file and the code from developemt.rb would load that  
global variable from the config file. I agree with it.
