SCons manual in "Scanner Objects" section says the following:
> Note that the file is not guaranteed to exist before the scanner is
> called, so the scanner function should check that if there's any
> chance that the scanned file might not exist (for example, if it's
> built from other files).
I have two questions about this:
1. What to do if such condition is detected? Is returning an empty list
2. Is scanner supposed to be called again once file is created?
