: << 'COMMENT'
Policy-script developed by Magenta ApS for Aarhus Municipal.
Learn more about Firefox "Policy Names" here:
https://github.com/mozilla/policy-templates/blob/master/README.md
It's only possible to have ONE policy-file. In the future this script 
should have to evolve to be a more dynamic solution if we want to be 
able to, e.g. use the same script accross machines and handpick which
Policies we want to use. Until then there will be set some default static
Policies with OS2borgerPC in mind.
