#
# Update localized NIBs
#
# Given a list of NIB file locations and a list of supported locales, this
# program will attempt to create or update the localized versions of these
# NIB files using the localized strings file associated with each NIB.
#
# Localized strings files for each nib are all placed under the project base
# directory, in <locale>.lproj/<CombinedDirectoryAndNibFileName>.strings.
# CombinedDirectoryAndNibFileName.strings is computed as such:
# <full_path_to_nib>.replace("/", "_").replace(".xib", ".strings")
# 
# If the strings file does not exist, this script will attempt to create it.
