While this can be disabled on local systems, it will be overwritten upon a git pull. We will pull source code from ../src and patches from ../patches. These patches will be applied here and the artifacts built up. +This is where to place any files to patch upstream projects. The patches are whole files and must be added with their full relative path. For example, if you're making applying a patch to onos/apps/vtn/vtnrsc/src/main/java/org/onosproject/vtnrsc, then you'll need that entire directory path here. Use copy and paste of the location after running "pwd".
