To find out how to use this package, you need to go into a locked filing cabinet in a room labelled 'Beware of the Leopard'. Having done that, you can run the tests using the following method:
sktest /dev/sdX short ; watch -d 'skdump /dev/sdX | head -n 20'
and then wait until the test completes (found on an ubuntu forum. Use sktest --help for other options.
If you are not building this as a required dependency of another application, it is generally much easier to use smartmontools http://sourceforge.net/apps/trac/smartmontools/wiki
