# This script converts the translation text files(.txt) into the (.fpb) files loaded by the game.
# Put translation files into ./script/en/
# Separate dialogues(a.k.a. "lines") in the translation files by using "<>".  Whitespace between the dialogues will get trimmed.
# Use newlines (\r\n) or "$n" to tell the game to split the dialogue onto a new line in the dialogue box.
#
# Usage:
#   ./txt2fpb.rb
