Hi Hans,

> \blackrule[width=10cm,height=1pt,depth=1pt,color=red]
That seems to work, thanks!

Is there any particular difference between all these line commands (\hairline,
\thinrule, \blackrule), apart from the options they support? Are they meant
for different situations, or is there some other reason why they exist next to
each other?

Gr.

Matthijs
