Hello
Is it possible to import a metapost extension into a file compiled with the lmtx engine ?
I tried unsuccessfully with this example :

%%%% begin test.tex

\starttext
\startMPcode
  input mp-scratch;

    Scratchversion:=3;

draw Drapeau;
draw Repeter("4");
draw Avancer("50");
draw Tournerd("90");
draw FinBlocRepeter;
 
\stopMPcode
\stoptext

%%%% end test.tex

Thanks

Fabrice
