Problem
ICON4Py's documentation, of every kind: the configuration language, the code,
and the science. None of it is written, and the pieces have different audiences
and different authors, so they are separate bets rather than one.
This was a pitch under "Replace blueline" until the cycles 37 and 38 sync. It is
a container, not a bet -- proj-c6be72 now depends on it instead of holding it,
which is the real relation: blueline cannot be replaced by something nobody can
read the documentation for.
