If I remember right, when the file is handed to the kernel, it looks for a
few magic bytes at the beginning of the file to determine if its a script,
who handles it, or what kind of binary it is.  Usually a strings command
on the file for the first line will tell the tale.  Also, this is a crude
way to find out what libraries and functions are called.
