fgmeta/python3-flightgear/fg-copy-weather-scenarios-to-default-locale
Florent Rougon d259ec0b76 i18n Python scripts: improve fg-copy-weather-scenarios-to-default-locale
- Use the new flightgear.meta.strutils.simplify() function.
- Automatically add a comment to the generated file to indicate that it
  was automatically generated and shouldn't be manually modified, etc.
- Improve error handling: abort with a clear error message if any of the
  'id', 'name' and 'desc' children of a 'scenario' element is
  problematic (empty or missing, for instance).
- Rename make_xml_leaf() to makeXmlLeaf() + other minor renaming.
