Each function needs a description, together with an explanation of all
parameters, return values, etc., etc. – just think of having a
HarfBuzz manpage.

This is certainly useful, too.  But I consider the `manpage'
documentation quest more important since there are already showcases
that demonstrate HarfBuzz quite well.
