README

Use these files in your app. Make a directory called en.lproj (and for each locale you wish to use). Use CPLocalizedString() in your code wherever you want a localized string.

Generating String Files
OS X Only
==========
cd My\ App
genstrings -o en.lproj -s CPLocalizedString *.j
==========
(Edit strings file in en.lproj/)
==========
cd en.lproj
plutil -convert xml1 Localizable.strings -o Localizable.xstrings
==========
(Add to allowed language file)
