True. However, the scheme is not quite consistent due to the following
-- When specifying stdout and stderr in command line, I do not specify them
in directories. Yet, if I map them in non-existent directories, Swift will
create those directories and put the stdout/stderr files in them. This does
not happen with other files even if they are specified in command line.
-- If a file is specified as output file in app definition but does not
appear in the command line, Swift will still bring it in as an output.
Again, this will happen only if the file is mapped at top level and not in

Yes. The app specifies it alright but the executable does not specify it on
