+//							Zip File Format Headers.
+//							***********************
+//
+// Current version: 1.00 BETA 2 (01/09/2003)
+//
+// Comment: Based on the ZIP file format specification from Appnote.txt
+//          from the PKZip Website on July 13, 1998.
+//          New implementations of the ZIP file format might not work
+//          correctly (ZIP64 ?).
+// 
+// History: - 1.00 BETA 2 (01/09/2003) - Use stdint.h sized types
+//          - 1.00 BETA 1 (12/06/2002) - First public release
