I am still dabbling with ConTeXt. There is a lot to learn, but it is worth
it. ;-}

At the moment I have (when finished I make a macro of it):
\startframedtext[middle]
  \startalignment[middle]
    {\bf A goal properly set is halfway reached.}
  \stopalignment
  \blank[small]
  \startalignment[flushright]
    {\it Abraham Lincoln}
  \stopalignment
\stopframedtext

I want to use this to intersperse my document with citations. It is not bad,
but I like to change two things:
- I would like to use rounded corners
- I would like to use a slightly thicker line to draw the box

How could I accomplish this?
