+# Version 0.2  2002-02-16  Jean Delvare <khali@linux-fr.org>
+#  Fixed to work with the new, simplified /proc interface names of the eeprom driver
+#  (lm_sensors 2.6.3 and greater.)
+#  Shifted data display by 4 columns left.
+# Version 0.3  2002-02-17  Jean Delvare <khali@linux-fr.org>
+#  Added UUID field at 0x10 (added decode_uuid.)
+#  Merged decode_string and decode_string32.
+#  Added unknown field at 0x20.
+#  Moved header and footer to BEGIN and END, respectivly.
+#  Reformated history to match those of the other decode scripts.
+#  Deleted decode_char (made useless by decode_string.)
+#  Reordered field display, changed some labels.
+#  Added old /proc interface check.
