+# PowerPoint generates SmartArt streams, like ppt/diagrams/data1.xml containing
+# UUIDs for each <dgm:pt> element. This makes it hard to reason about them,
+# referring to numerical identifiers is just easier in notes. This script
+# replaces UUIDs with integers, which is the style used in the OOXML spec as
+# well.
