you mean you explicitly specify a target "x" on the command line, but you don't know whether it's a File or a Dir?
Can you come up with a short user scenario for this? What is it that you're trying to accomplish?

I think we had this discussion some time ago when you asked about how to traverse the Node tree (DAG), the single Nodes are mainly 
addressed (identified) by their full path (relative path and name) relative to the top-level folder of the current SCons build. This 
is what's used while looking up Nodes (exists already, or not?) in the internal FS tree structure, such that we are able to 
distinguish between "vector.h" in two different subdirectories for example.

Hope this helps you a little further.

Best regards,

Dirk
