linux is in swap --- yes or no?

[nigel@turbo10.com]

Hi,

    	I'm trying to work out whether or not a Linux server is using swap.

 	"top" and "free" seem to give equivocal results - vmstat too.

 	How can I at any instant in time say are you in swap - yes or no?

 	I was hoping this module ...

 		http://search.cpan.org/~bloonix/Sys-Statistics-Linux-0.08/

 	... would give a definitive yes/no answer but it seems to also be 
a bit fuzzy when it comes to this question.

 	Any thoughts?
