========================================================================

* In emacs via imaxima, the Maxima info tree *is* reacheable through the menu
entry.
* Both in imaxima and in console, the online help is unusable (see above).

   * What led up to the situation?

Installing latest maxima packages from unstable on top of a current Stretch
system.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Nothing
