# This file must be placed inside the /plugin-folder/language/ folder
#
# Excecute from plugin root folder with ". languages/make-pot.sh"
# Check if executed from root, if not moves up one folder and
# check if current folder has name matching php file to make sure
# we're in the plugin's root folder.
# If NOT it'll close the terminal.
#
# If no existing language template file (*.pot) exists, create it and
# default .po and .mo, otherwise,
# Give user the option to merge old template with new (updatesd default po & mo also).
#
# Check if there's existing language packe, e.g. text-domain-fr_FR, and
# give user the option to update and merge.
