desc 'purge-kernels', 'Purge linux kernels older than the current one'
long_desc <<-LONGDESC
Example: `sudo geordi purge-kernels`

/boot quickly gets cluttered with unused old kernels, finally rendering your
machine unable to install updates.

This script will retrieve and print a list of all current or older kernels. If
confirmed, it will then purge all kernels older than the current one.
