I was looking for detailed documentation on token handling plugins but not
finding it.  Am I missing it?   Is it in the man page or the luks2 pdf or
the wiki or the readme? or somewhere else?

In lieu of the docs I plan to start some code and communicate with the
mailing list but given the problems with the mailing list lately I am
waiting.  (I keep getting kicked off--both email addresses).
