Handle JSON property list format

[briandfoy]

• Where is that documented
• How can I read it?
• How can I write it?

To reverse engineer it, you can convert an existing property list to JSON. Remember that the plutil command replaces the original content if you don't use the -o switch:

% plutil -convert json -o plist.json some.plist

But, not everything that was valid Property List data in XML or binary is valid in JSON. I don't know what those are, but plutil will complain.
