We use a variety of tools to convert node names to title case and then enumerate them in this inventory.
s/ ([a-z])/ \u$1/
I realized after changing the case in my Graphviz diagram that this was sufficient or necessary to have my part descriptions use title case.
perl -ne 'print "$&\n" for /[A-Z][a-z]+/g' |\ sort | uniq
So I created this inventory and clicked each link to make a properly titled page.
