Write your installation script so that it does things in the following order:

  1. Deletes the existing CGI scripts
  2. Pause for one second
  3. Deletes the existing modules
  4. Installs replacement modules
  5. Installs replacement CGI scripts
package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
