−# 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.
+
−# - (Optional) Change LOCALEFILES below to limit the number of locale files to update
+
−# Result: All .lua files in share/hedgewars/Data/Locale will be updated.
+
−
+
−# SETTINGS:
+
−# Space-separated list of locale files to update, or *.lua for all.
+
−# (Note: always include stub.lua)
+
−LOCALEFILES="*.lua"

+
−# END OF SETTINGS

−# 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!
