#!/usr/bin/env bash
# Usage: sh resign_ipa.sh <IPA file> <full build version>
# i.e.: sh resign_ipa.sh ~/Downloads/Wolf.ipa 2.6.11.914
# Repackages and resigns the ~/Downloads/Wolf.ipa file and deposits the resulting file at ~/WolfBuilds/Wolf.2.6.11.914.ipa
# fail if any commands fails
set -e
# debug log
