+
+ 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
