need.txt = version that is to be patched. 
data, the patches = your.txt = version which was already patched. 
In the data folder, the file must be named always 001,002,003 etc.
If the patch is about 009, he must not 010 hot but 0010, so always 2 "zeros" are available. 
The same thing also about 0099. ;) Folder create the dump in the client: if not already present. 
create your.txt & need.txt. In both documents, a 0 write purely so that you let out a patch, then everything is made.
