unlang equivalent of radlog

[Nasser Heidari]

Hi, 

I have several Perl modules running on my Radius server, I'm going to remove
them all and use unlang instead. I have two questions:

	1- The reason that I'm going to change Perl modules with unlang is
Performance ! I think unlang should have better performance in comparison to
Perl (Note that I have some mysql queries in my perl modules), is this
correct?
	2- I have used &radius::radlog in my perl modules to  log some cases
on radius.log, is there any equivalent for it in unlang? Could you please
kindly give an example?

Regards,
Nasser
