Here mtxrun is a lua script. In order to avoid the usage of a cmd

+ file on windows this runner will start texlua directly. If the
+ shared library luatex.dll is available, texlua will be started in

it will be spawned in a new proces.
We also don't want to use other runners, like those that use kpse
to locate the script as this is exactly what mtxrun itself is doing
already. Therefore the runscript program is adapted to a more direct
approach suitable for mtxrun.
