Comment (by ryandesign):

 Flags that go after `port` and before the action verb use a single dash
 and a single character, e.g. `sudo port -n upgrade`. Flags that go after
 the action verb use two dashes and multiple characters, e.g. `sudo port
 upgrade --enforce-variants`. So, if you are introducing a new flag to
 force activations, and it applies to only the activate verb, then it
 should be named `--force`, not `-f`.
