When there are classes outside packages, scaladoc should either support them or report a warning or error.

2.5.0-RC1 reports an exception.




Using 2.4.0-final  (under cygwin on Windows)

$ ls
NoPackage.scala

$ cat NoPackage.scala

class NoPackage {}

$ scaladoc -version
Scala compiler version 2.4.0-final -- (c) 2002-2007 LAMP/EPFL

$ scaladoc NoPackage.scala
error: Resource file 'style.css' not found
error: Resource file 'script.js' not found
two errors found

(ignore these errors - already fixed in bug 1054)


(The generated pages aren't particularly useful: no mention of NoPackage.)



Using 2.5.0-RC1  (under cygwin on Windows)

$ scaladoc -version
Scala compiler version 2.5.0-RC1 -- (c) 2002-2007 LAMP/EPFL

$ scaladoc NoPackage.scala
