+# To avoid gotchas copy the board file into t.brd, it will be edited in place.
+# Once you happy with fixes overwrite the original eagle board file with t.brd
+
+# Look thought the diff and file list of parts with updated values
+git diff | grep '+<part name="' |sed s/'+<part name="\([^"]*\)".*value="\([^"]*\).*'/'\1 \2'/ >part.list
