IMO, "5 lines instead of 2 lines" isn't the kind of reasoning that is useful.  
Otherwise we would never do [[ 
https://www.industriallogic.com/xp/refactoring/composeMethod.html | Compose 
Method ]] on a long method since the act of breaking a long method down into a 
bunch of smaller methods necessarily introduces more lines of code.

This script originally was one giant function that did everything.  A bunch of 
things need to be done twice now: one for the source file and once for the 
header file.  Applying Compose Method Extracting results in extracting a group 
of smaller functions/methods.

Now the functions have a bunch of state that needs to be passed around between 
them and the functions might be more clearly expressed as methods on a class, 
but I didn't go that far with it.
