	mirror_tests is designed to check that yaffs behaves the same way as linux.
	This is done by applying the same command to both linux and yaffs and 
	then checking the output of the functions.
	The default place for creating linux files is direct/timothy_tests/mirror_tests/tests/
	This directory is removed and is recreated at the beginning of each test, 
	However some of the files may be read only and cannot be deleted.
	It is much better to remove this directory via the command line.

	rm test/*;rmdir test/;./mirror_tests -n 100 -v
