cygrunsrv: trailing command line arguyments not allowed

[enrique@perezterron.net]

Hello,

I am trying to install a service manually in an attempt to understand 
why cron-config did not work for me.

So, I did this:

> $ net stop cron
> Tjenesten Cron daemon stopper .
> Tjenesten Cron daemon ble stoppet.
> 
> $ cygrunsrv -R cron
> 
> $ cygrunsrv -I -p /usr/sbin/cron.exe -a -n
> cygrunsrv: Trailing commandline arguments not allowed
> Try `cygrunsrv --help' for more information.

I also tried a number of other combinations and orders of arguments, all 
with similar results.

What am I doing wrong?

Thanks
