+ will not copy hidden (./) directories if used.
+
+ -o [yaffs_path]
+ chooses the path where the branch will be copyied into yaffs.
+ note this path must start with "/yaffs2/"
+ example: python yaffs_importer.py /home/timothy/work/yaffs/yaffs_importer_test_dir -o /yaffs2/apple/
+
+ -yaffs_trace [number]
+ this sets the yaffs_trace() function with the number inputed.
+ this number must be in the range of char.
+ yaffs_importer saves the current yaffs_trace value and restores the value after the branch has been imported.
+ setting this flag to -1 will run yaffs_importer with the default yaffs_trace value.
+
+Deleting files and folders
+ to deleate files and folders in yaffs use the yaffs_browser (the documentation still needs to be written).
+ to run the browser use this: "python yaffs_browser"
+ to deleate a file or a folder select the file or folder then go
+ Edit->Delete selected.
+
+Clear Yaffs
+ the easiest way to clear the yaffs file system of all files and folders is to remove
+ the emfile-2k-0 file. this file is stored in the
+ yaffs2/direct/python/ folder.
+ the command is: rm emfile-2k-0
+
