-Run a Matlab script.
-
-Note that the script is run in the directory where it lives -- Matlab won't
-allow it any other way.
-
-For error-catching purposes, keep an own log-file that is destroyed if the
-task finished without error. If not, it will show up as mscript_[index].log
-in the bldnode directory.

-Usage::
