The IsExecutable(file) command returns true if the user has execute permission for the specified file.  If the user does not, false is returned.

On Windows systems, the executable status of a file is determined by the file extension.  This may falsely return true for incorrectly named files.

If the file does not exist or an invalid file descriptor is passed, an exception is raised.
