*** =============================== ***
*** This is the arc42-FAQ copy task ***
*** =============================== ***

It will do the following stuff:

1.) copy all markdown files containing FAQs.
2.) removing heading and section numbers, which are explicitely included
in the arc42-in-practice book.
3.) copy all images or diagrams required.

To do this, it requires the git repositories for 'arc42-in-practice'
and 'arc42-FAQ' checked out next to each other.

You can execute it by 'gradle copyFAQ'
