# Script to update all Lua locale files.

# It's Clunky and slow!

# Note this script may sooner or later be phased out when we move to Gettext.

# HOW TO USE:

# - Run this script in the tools/ directory.

# - All .lua files in share/hedgewars/Data/Locale will be updated.

# - Change LOCALEFILES below to limit the number of locale files to update

# Space-separated list of locale files to update, or *.lua for all.

# (Note: always include stub.lua)

LOCALEFILES="*.lua"

# List of all Lua files to scan:

# * Missions

# * Campaign missions

# * Lua libraries

# * Styles (aka multiplayer scripts)

# * Mission maps

# IMPORTANT: Don't forget to update this list when new places for Lua

#            directories have been added!
