How to use external annotation on command line?

Evgeny,

Please forgive my nooby questions, but I am at lost as what to do. The helppage says:

  -annotations [String] paths to external annotations

So what value to pass to -annotations option? You said value should be like "-classpath"? So I add directories paths separated by path separator? What content should these directory contain? Jar file?

I asked similar question in here: http://blog.jetbrains.com/kotlin/using-external-annotations, but Andrey seems to indicate that we need an XML file for command line usage? So how do I generate this XML file? And where would I put this file to be used by compiler?

Thanks,
Zemian
