# -*- coding: utf-8 -*- This is a utility function used to manually set the flag noupdate to False on tags and account tax templates on localization modules     that need migration (for example in case of VAT report improvements) This is a utility function to help migrate the tags of taxes when the localization has been modified on stable version. If     called accordingly in a post_init_hooked function, it will reset the tags set on taxes as per their equivalent template.      Note: This unusual decision has been made in order to help the improvement of VAT reports on version 9.0, to have them more flexible     and working out of the box when people are creating/using new taxes.
