I am using the following preamble to put a frame around verbatim text. How
can I have all the text start some 5pt from the frame and how can I get
rounded corners, corner=0 does not seem to work



\setupcolors[state=start]

\setupcolor[xwi]

\definetextbackground
  [Code]
  [frame=on,
   framecolor=black,
   %corner=0,
   %offset=10pt,
   background=color,
   backgroundcolor=gray,
   location=paragraph]

\setuptyping
  [before={\blank\starttextbackground[Code]},
   after={\stoptextbackground\blank}]

\starttext

\starttyping
example
\stoptyping

\stoptext
