That's part of the build, not (directly) part of Kotlin itself.
Anyway, I'd highly recommend following the convention from the docs.

It seems that if it is a single class file, then it matches its name of the class (which start with capital letters), But if the file contains multiple declarations it uses initial lowercase.
That's what I can reckon from the presented sample.
