I didn't mean the command line switches are undocumented. I would
expect that to be documented elsewhere (e.g., mpost --help). I
meant that the 4 metapost commands to set the mode, namely
   batchmode
   errorstopmode
   nonstopmode
   scrollmode
are not documented. In case others don't know this: you can put
   scrollmode;
in your mp source, with behavior exactly like putting \scrollmode
in your tex source. This set of commands is omitted from mpman
and I don't think it should be.

They are listed in the syntax diagram for <message command>. For
now, a link to that would be expected.

That seems a good idea.
