Patch is useda lot for source code patches since it saves time and space. Imaginea package that is 1MB in size. The next version of that packageonly has changes in two files of the first version. It can be shipped as anentirely new package of 1MB or just as a patch file of 1KB which willupdate the first version to make it identical to the second version.
