Hi,

I have MetaPost graphics that are generated by an external program.
Each graphic is an individual file and the code is enclosed by

  beginfig(1)
    …
  endfig;
  end

The beginfig argument is always “1”, it does not increment.
Including the graphics using MPrun fails, since the first figure's
“end” stops the MetaPost run:

\startMPrun{foo}
  beginfig(1);
    fill fullcircle scaled 1cm withcolor blue;
  endfig;
  end; %% prevents the second graph from being processed
\stopMPrun

\startMPrun{bar}
  beginfig(1);
    fill unitsquare scaled 2cm withcolor red;
  endfig;
  end;
\stopMPrun

\starttext
  foo: \externalfigure[mprun:foo.1]
  bar: \externalfigure[mprun:bar.1] %% not shown
\stoptext

I want to avoid preprocessing the generated MP graphics, if possible
(stripping the “end”s). What is the best way to deal with these
graphics?
