# dcxibupdater - Danger Cove Xib Updater
#
# Updates all your localized Xibs in your Xcode project using Git and ibtool.
#
# Prerequisites and setup:
# - Xcode project stored in Git
# - Localized .xib files
# - IMPORTANT: Add *_prev.xib to your .gitignore
#
# Usage:
# 1.  Copy the script into a file called dcxibupdater.
# 2.  Make it executable (chmod a+x dcxibupdater).
# 3.  Add dcxibupdater to your $PATH (e.g. /usr/bin, /usr/local/bin).
# 4.  Go to root of your project (where the .git folder is).
# 5.  Make sure the current state of your Xib(s) is commited to Git.
# 6.  Start editing the English Xibs and save your changes.
# 7.  DO NOT commit to Git just yet.
# 8.  Run dcxibupdater.
# 9.  Check the localized Xibs to see they're updated.
# 10. Commit your changes. Repeat.
#
# Current state:
# - Tested to work in a simple project, localized to two languages.
# - NOTICE: en is the default language.
