+This is a specially modified version of Image-ExifTool that allows to
+make byte exact copies of the Minolta Dimage A1 camera original from a
+copy edited by exiftool >= 7.34.
+
+If you set environment variable MINOLTA_BYTE_EXACT=4 and then remove all
+tags you added, you will get a copy, that is equal to the original file
+as it came from the camera.

+exiftool minolta A1 byte-exact
+==============================
+
+This version of exiftool allows to make byte exact copies of the Minolta
+Dimage A1 camera original from a copy edited by exiftool >= 7.34.
+
+If you set environment variable MINOLTA_BYTE_EXACT=4 and then remove all
+tags you added, you will get a copy, that is equal to the original file
+as it came from the camera.
+
+Author: Stanislav Brabec <utx@penguin.cz>
+
+Variable MINOLTA_BYTE_EXACT meanings:
+0 or undefined: default exiftool behavior
+1: organize tags exactly as camera does
+4: 1 + pad items exactly as camera does
+Notes:
+ - To get byte-exact copy of original, you have to strip custom tags and
+   revert existing tags manually, as levels 2 and 3 are not yet
+   implemented.
+ - For exiftool >= 7.34 you can get byte exact copy of original even
+   from files, that were written by with the default exiftool behavior.
+ - exiftool <= 7.34 has an one obsolete pad byte in the MakerNotes, which
+   causes a different result after reverting of all tags.
