+Extended 2 filesystem structure definitions for ext2ed.
+
+Most of this file is just copied from the ext2 main include file.
+
+My parser is very primitive - It only searches for the struct keywords,
+and uses the variables in there. The rest of the file is just ignored.
+
+You will find at the end a few additional types which are not available in
+the original include file, such as the types "file" and "dir". They have
+no variables, but are necessary due to the way ext2ed binds C commands
+to specific types.
