    When a child is born the neighbours come to visit the new
    parents. The women come to admire the baby and the men come to
    judge the baby (if it is a boy) if he will become a strong man.
    The neighbours will bring a {\em krentenwegge} along. A
    krentenwegge is a loaf of currant bread of about \unit{1 meter}
    long. Of course the birth is celebrated with {\em jenever}.

    Smaller communities used to be very dependent on the
    cooperation among the members for their well being. Members of
    the {\em nabuurschap} helped each other in difficult times
    during harvest times, funerals or any hardship that fell upon
    the community.

    When people turn 50 in Hasselt it is said that they see Abraham
    or Sarah. The custom is to give these people a {\em speculaas}
    Abraham or a Sarah. Speculaas is a kind of hard spiced biscuit.

I did not try all example, but this seems to work here. Can you
provide a minimal example and say what you expect to be different?

Hans and Alan are in the process of completely re-writing the
chemical macros. I don't know the current state.

In MkIV there's a new syntax you can use:

\startlinealignment [left]
  \inframed[width=fit]{People in Hasselt}
\stoplinealignment

\startlinealignment [middle]
  \inframed[height=1.5cm,frame=on]{have a}
\stoplinealignment

\startlinealignment [right]
  \inframed[background=screen]{historic background}
\stoplinealignment

I did not investigate why the middle alignment is on the same line
as the left alignment and if that's intended or not.

I'm afraid there are none (and probably never will be). The wiki
improved an awful lot during the last months, especially the command
reference. There's also the revised manual, tex.stackexchange and of
course the mailing list.
