# Toto je autorun-script na kontrolu nahodeneho scriptu. Funguje tak, ze
# ku kazdemu scriptu, ktory chceme kontrolovat musime vytvorit jeden
# takyto autorun-script. Tento autorun-script zapiseme do crontab. Potom 
# bude v pravidelnych casovych intevaloch kontrolovat nas script, ci bezi. 
# Pokial script nebezi, tak ho autorun-script znovu nahodi.

# Adresar spustaneho scriptu.
