Review comment:
Yep. I agree with @mik-laj this is a much better approach. It makes it
much more readable if the code to execute is in separate functions for each
options. It's pretty natural evolution when the command line options become
more complex. When you start, it's easier to add hand-written stuff, and keep
code "together" but once you start adding functionality there is a need at some
point in time (now !) to split it into smaller, independent methods. The next
step is to split it into separate modules, but we are far from that!
