# Localize.py - Incremental localization on XCode projects
# João Moreno 2009
# http://joaomoreno.com/
# Modified by Steve Streeting 2010 http://www.stevestreeting.com
# Changes
# - Use .strings files encoded as UTF-8
# This is useful because Mercurial and Git treat UTF-16 as binary and can't
# diff/merge them. For use on iPhone you can run an iconv script during build to
# convert back to UTF-16 (Mac OS X will happily use UTF-8 .strings files).
# - Clean up .old and .new files once we're done
# Modified by Yoichi Tagaya 2015 http://github.com/yoichitgy
# Changes
# - Use command line arguments to execute as `mergegenstrings.py path routine`
# path: Path to the directory containing source files and lproj directories.
# routine: Routine argument for genstrings command specified with '-s' option.
# - Support both .swift and .m files.
# - Support .storyboard and .xib files.
