A patch +file usually is a list created by the diff program that contains +instructions on how an original file needs to be modified. Patch is used +a lot for source code patches since it saves time and space. Imagine +you have a package that is 1MB in size. The next version of that package +only has changes in two files of the first version. You can ship an +entirely new package of 1MB or provide a patch file of 1KB which will +update the first version to make it identical to the second version. So +if you have downloaded the first version already, a patch file can +save you a second large download. +</para> + +</sect2> + |
