Standard init scripts use some common functions to write the process ID 
of the running program in a standard place so the 'stop' operation can 
find it.  A side effect of this is that if you have multiple instances 
of a program running you have to have separate init scripts with 
different names to control them.   Also, you generally need root access 
to start/stop with this facility.  If your program doesn't otherwise 
need root access and you want an ordinary user to have control you may 
want to do it some other way.
