Smartcard Linux stack diagram?

[Daniel Pocock]

I came across this diagram of the stack including OpenSC and GnuPG:

Is this still accurate?

I notice a couple of small things missing:

Scute: it should be a link between gpg-agent and NSS?

StrongSWAN: it depends on PKCS#11 directly (not using NSS)

The PKCS#11 interface could be labeled "Cryptoki / PKCS#11"

I'm thinking about making a slightly more up to date diagram with a
slightly different style - but if something else already exists, please
feel free to point it out.
