1. en_AU English (Australian)

it's real language in Gramps?

I not see it in /po/ dirs.

Can I delete this language from list?

2. I can't run this:

# check localisation percentage

for file in *.po; do echo -n "${file} "; ./check_po -s ${file} | grep "Localized at"; done

But nice work this:

# check localisation percentage

for file in *.po; do echo -n "${file} "; python3 ./check_po -s ${file} | grep "Localized at"; done

What must be?

And file 'check_po' must be 'check_po' or 'check_po.py'?
