generate_locales_map.py

# This file is intended for those who will add a new language
# to the i18n.ini file or contribute to the i18n.py file. 
# Translators should run this file after adding a new language
# and replace the locales_map variable in i18n.py with the one 
# printed by the program before submitting a PR. 

# The created locales_map variable will be used for 
# selecting languages in the 'advanced' tab of the application.

# The reason Babel library is not included in the final packaged app
# is that it increases the program's size by approximately 30mb due to locale data.
