#!/bin/bash
# Script to generate mac application bundles for KOReader
#
# We don't use XCode at all. Just commandline tools.
#
# menu.xml contains the main menu of a typical OSX program.
# each time some user facing string in menu.xml changed we can
# generate a new translation template with:
#
#  cp menu.xml menu.xib
#  ibtool --generate-strings-file mac.strings menu.xib
#  rm -rf menu.xib
#
# the generated "mac.strings" is in xliff format (binary, not plain text)
# and can be translated using an xliff editor or an online service that support
# IOS string format, like weblate.
