		- symbolic link
		- the file a symbolic link is linked to
		- what type of path the symbolic link is
		- regular file
		- block device
		- character device
		- directory
		- readable
		- writable
		- executable, if it's a regular file
		- searchable, if it's a directory
		- the owner of the file, if it's not accessible
		
		If the file does not exist it will say so
		It will also tell you off, if you are childish...
