Thanks for the link, the suggestion of depends_on does look to be a
good thing in our context, it will break the ABI though so it's not an

If you don't have any custom nodes then you could use the .ive format,

very simple.
As for the .ive format, I'll do a bit of googling
Hi Andy,
It does sounds like .ive should foot the bill for you as your just
