@mateiz My concern is that whether we want to encourage users to use those
main methods if we know they are definitely going to change in the next
release. Now the main methods take arguments in a predefined order. It is hard
to remember and there is no help message.
I'm testing scopt for parsing options:
https://github.com/mengxr/MLlib-QA/blob/master/src/main/scala/mllib/qa/BinaryClassification.scala
The question is whether we want to make the change now or in the next
release.
