When compressing, it is possible to tell the tool to add an entry to the MD5 file (index 1), it is still necessary to give an empty file for that index. To do so, pass the option "-z idx,name" insteas of "-z idx". This will create an entry of the form "size md5 name". For instance "-z 6,system.img". When decompressing, if one passes "-z idx,name" instead of "-z idx", the tool will decompress and check against the value in the MD5 file. Change-Id: Ifb945f6121644ae9105265d2d83ce6067301c5b2
