Subject: implemented attribute mapping and chmod. file attributes are mapped
 in the same manner as smbd. See the README for a full explanation. (This used
 to be commit 0a5dcddd3fa23081d7cd214acc32b8046125a74e)

+ATTRIBUTE MAPPING
+-----------------
+
+smbwrapper does an inverse attribute maping to what Samba does. This
+means that the archive bit appears as the user execute bit, the system
+bit appears as the group execute bit and the hidden bit appears as the
+other execute bit. You can control these with chmod. The mapping can
+be enabled an disabled using the normal smb.conf controls (ie. "map
+archive", "map system" and "map hidden").
+
+Read-only files appear as non-writeable by everyone. Writeable files
+appear as writeable by the current user.
