"""
|

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.
|
|
|
