Translations
.pot files are translation templates.
.po files contain human-editable translations, which are compiled to .mo bytecode.
If you edit any .po file, to see the changes ingame you need to run setup.py build_i18n.
If you change or add translatable content in py, xml, yaml (not scenarios) or sql files, run
[development/create_pot.sh] (../tree/master/development/create_pot.sh) to also update the templates.
There are different helper files for gathering all data from those sources in one place.
If you are interested, check the extract_strings_ files in development/.
When you (for example) change or add strings in the file tutorial_en.yaml,
run [development/create_scenario_pot.sh tutorial] (../tree/master/development/create_scenario_pot.sh).
To make the .po translation files aware of changes in the template, run
[development/update_translations.py] (../tree/master/development/update_translations.py).
[msginit -i "inputfile.pot" -l "languagecode" --no-translator -o]
