Another approach worth considering is to wrap the servlets up in a
model. This often takes a bit longer and more thinking in the set-up
phase but will give you code that is easier to reuse in other places.
I've done this kind of problem both ways and either is fine but I'd
lean to the model. You would end up with something you could run with
Catalyst/Flea/Mojolicious/in-line-plack-with-auth-middleware/command-line/whatever.
