# 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.
