st: help file for kernreg2

[Berk Sensoy <berksensoy@gmail.com>]

Hello

I have installed kernreg2 using ssc install.  However, there does not
seem to be a help file associated with it so I'm having trouble
figuring out the syntax to use to invoke the command.

For example typing kernreg X Y produces the error:

"option bwidth() required"

Thanks!
