+  If MPXFILE is older than MPFILE, translate the labels from the MetaPost
+  input file MPFIle to low-level commands in MPXFILE, by running
+    $MPTOTEX, $TEX, and $DVITOMP
+  by default; or, if -troff is specified,
+    $MPTOTR, $TROFF, and $DMP.
+
+  The current directory is used for writing temporary files.  Errors are
+  left in mpxerr.{tex,log,dvi}.
+
+  If the file named in \$MPTEXPRE (mptexpre.tex by default) exists, it is
+  prepended to the output in tex mode.
