Hi Willi, all,
Thank you for your answer but it doesn't work... I need it quickly, so
I've a solution but it's not, hum, very clean since I don't know
metapost very well:
\def\followtokens#1%
{\vbox\bgroup
\forgetall
\dontcomplain
\startMPenvironment
\doifundefined{RotFont}{\definefont[RotFont][RegularBold]}
\stopMPenvironment
\MPtoks\emptytoks
\resetMPdrawing
\startMPdrawing
\includeMPgraphic{followtokens}
picture pic[] ; numeric len[], n ; n := 0 ;
\stopMPdrawing
\handletokens#1\with\processfollowingtoken
\startMPdrawing
if unknown RotPath : path RotPath ; RotPath := origin ; fi ;
if unknown RotColor : color RotColor ; RotColor := (0,.625,0) ;
fi ; % mygreen
if unknown TraceRot : boolean TraceRot ; TraceRot := false ; fi ;
...

Hi Renaud,
you can define a color with
\definecolor[brown] [r=.9,g=.8,b=0.6]
in your MEATPOST code you can say things like
drawoptions(withcolor \MPcolor{brown}) i.e. that all will be
drawn in borwn
draw ... withcolor \MPcolor{brown} i.e. append the color to the
drawing statement.
Willi
