| 2 | #patches themselves are specified in XML in a separate file that must |
| 3 | #be in SRC_URI and end in .patch.xml. The patch XML file must also |
| 4 | #have a <targetFile> element that specifies the base name of the file |
| 5 | #that needs to be patched. |

| 7 | #See patchxml.py for details on the XML patch format. |
