Convert any Windows app or script to a service

I've just found very nice utility allowing to convert any Windows application or script into a Windows service:
http://nssm.cc/
NSSM stands for "the Non-Sucking Service Manager"
It has many clever options for such a small and lightweight application (230k EXE file)
Web site is brief but explains all important ideas.
I'll definitely use this utility instead of other "reinvented wheels".
