They kind of glossed over the real value, which is using it as a template to automate a step at a time:

"Each step of the procedure is now encapsulated in a function, which makes it possible to replace the text in any given step with code that performs the action automatically."

It breaks the work down into more manageable tasks. I probably wouldn't give it to users until it was done, but putting placeholder functions is a common strategy.

It's probably to allow for added complexity as they expand on each task. Makes it simpler to import elsewhere too.

Enough sed.

Techno, dubstep, various game OST's, some metal, orchestral, and various pop songs my partner turned me on to. Quite a few touhou remixes too.
