+Subject: [PATCH 3/4] swtpm_setup: replace dep on JSON-GLib with
+ sheredom/json.h
+
+Turns out swtpm_setup requests capability info from `swtpm` by shelling
+out to it then parsing JSON output.
+
+Pulling in JSON-Glib as a library sounds like pain. Let's just use a
+simple single-file JSON parser library.
+
+There will be no comment on using JSON for this from me.
