Team's Response

Hi!

You are right in that the meaning of the command does not change. Yet, this will not affect the usage for our users, especially not users who have grown accustomed to our command line interface. We take your suggestion into consideration, but for our 1.6 release, we have set it that commands should be in lower case.
