Pass arguments to Ruby when running Rails

When I run rails server, rails console, rails runner, etc., I want to pass some command-line switches to the Ruby binary. (In my case it's JRuby and I want to make sure Java starts up with more memory, but this question seems like it could apply to any Ruby implementation.) Surprisingly I can't find any documentation about this. Anyone know how to do it?
