Patch in 5 minutes

This document discusses software patching and provides instructions for creating a patch file. A patch fixes specific bugs by making changes to code between different versions. To create a patch file, the "svn diff" command is used to output the differences between two revisions into a file, and then the "patch" command applies that file to update the code to the fixed version. The commands must be run from the same directory for the patch to be applied correctly.
