|
Makes an unified diff containing differences between <parameter>old_file</parameter> and
|
|
<parameter>new_file</parameter> and stores it in <parameter>dest</parameter> file. The
|
|
resulting file is human-readable. An optional <parameter>context</parameter> parameter
|
|
specifies how many lines of context should be added around each change.
|
|
Setting <parameter>minimal</parameter> parameter to true will result in outputting the shortest
|
|
patch file possible (can take a long time).
