There seems to be an error concerning files with a 'd' as last character in the filename.
E.g.: When a file is called myFile.ts everything works fine and a myFile.js is created, but when it is called myFiled.ts it is not transpiled and there is no myFiled.js.
I suspect that there is a problem with the logic that should find description files. Maybe you're looking for *d.ts instead of *.d.ts?
