Feature: Different short and long switches

Feature Request

This is something that I have ran into several times.

Please allow us to use custom short switches for long arguments.

app.js --page
app.js --package
app.js --port

Currently, it gives -p and -P randomly for the three arguments.

I would like to have these:

app.js -n, --page
app.js -m, --package
app.js -p, --port
