#This class applies patches to an XML file during do_patch(). The
#patches themselves are specified in XML in a separate file that must
#be in SRC_URI and end in .patch.xml. The patch XML file must also
#have a <targetFile> element that specifies the base name of the file
#that needs to be patched.
#
#See patchxml.py for details on the XML patch format.
