How to use swapspace application?

I have installed swapspace a few weeks back. I have followed this answer for installing swapspace in my ubuntu 14.04

sudo apt-get install swapspace
#confirmed installation using "man swapspace"

I have used this application because it will dynamically make a swap space as per the system requirement and also I find the manual creation of swap space daunting.

But after a fresh reboot when I tried to find my swap space using these commands

$ swapon -s
Filename                Type        Size    Used    Priority

$ free -m
Swap:            0          0          0

shows no swap space in my system?

How should I use swapspace?
