The twistd API is almost non-existent, unfortunately. However, you can
get a long way by doing something like this in your "main script":

from twisted.scripts.twistd import run
sys.argv[1:] = ["pluginname", "-whatever"]
run()

It's decidedly a hack, but it works and relies only on public APIs, so
it's tolerable until we get a better API.
