<para>The patch program modifies a file according to a patch file. 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
|
|
a package that is 1 MB in size. The next version of that package
|
|
only has changes in two files of the first version. It can be shipped as an
|
|
entirely new package of 1 MB or just as a patch file of 1 KB, which will
|
|
update the first version to make it identical to the second version. So
|
|
if the first version was downloaded already, a patch file avoids
|
|
a second large download.</para></sect4>
