+# 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.
