+## Static data needed for pkh operations
+## Instead of hardcoding the data in code, data files allow to quickly
+## update and maintain such data in one unique place
+## The goal is to have the minimal possible set of data necessary
+## to grab the actual data. For example we don't want to store every Ubuntu
+## or Debian series, but rather an URL where we can properly access that data.
