#+  Usage: check-job-board-tags [-h|--help|-l|--list-only]
#+  -
#+  Performs a series of assertions about the relationship between
#+  different stacks' languages and features.  Some stacks are intended to be
#+  subsets of others.  Some stacks are meant to be mutually exclusive.  These
#+  relationships are checked via the assert-job-board-tags script, which
#+  accepts batch inputs created by *this* script.
