Hi all,

I've been trying to create a horizontal rule of limited width, using MkIV. My
best approach so far is using a \framed with only a bottom frame:

  \framed[frame=off,bottomframe=on,width=.5\textwidth]{}

However, this is not quite elegant. Context provides two commands for drawing
lines, \hairline and \thinrule (which seem to do the same from looking at
their definition in pack-rul.mkiv, though \hairline does not seem to respond
to \setupthinrules for some reason I cannot discern...).

However, \setupthinrules accepts a lot of options (including height and depth,
which get passed to \hrule, but there is no width option (nor does there seem
any way to get \thinrule to pass a width to \hrule).

Another attempt to put a frameless \framed around the \hairline (which gets as
wide as the containing box) failed as well. The line kept getting vertical,
even when I sprinkeled some \dontleavehmod or \pars around...

Any suggestions on how to do this?

Gr.
