### BEGIN CUSTOMIZATION
|
||
### This file contains LibreOffice-specific rule customizations.
|
||
###
|
||
### To aid future maintainability:
|
||
### - The change location should be bracketed by comments of this form.
|
||
### - The original rule should be commented out, and the modified rule placed alongside.
|
||
### - By doing this, maintainers can more easily compare to an upstream baseline.
