+README version 0.4
+==================
+
+
+
+README version 0.3
+==================
+
+There're only little changes; Make the open_inode() function looks much 
+simpiler by breaking it into more subfunctions, so two new functions 
+introduced, they are:
+ 1) struct ext2_group_desc* get_group_desc(blokc_num);
+ 2) void read_inode(....);
+then a little more change on making it more C like.
