Some macros (Metafun)

Some macros (Metafun)

Hello,
In the Metafun manual, Hans uses macros like drawpath p ; drawcontrollines
p ; drawpoints p ; drawcontrolpoints p ...
How to use them in a document ?
Where to find source codes ?
For example, the following code does not work :

\starttext
\startuseMPgraphic{path}
   path p ; p := (1cm,1cm)--(1.5cm,1.5cm)..(2cm,0cm)..cycle ;
\stopuseMPgraphic

\startMPcode
  p := p .. cycle ; swappointlabels := true ;
  drawpath p ;
\stopMPcode
\stoptext


Thank you
Fabrice

     drawpath p ;
     drawpoints p ;
     drawpointlabels p ;
     drawcontrolpoints p ;
     drawcontrollines p ;
\stopMPcode

\stoptext

Hi Hans,
Sorry but I did not see your email.
What is the default color used to draw the path p ?
Thank you.
