# Usage:

# 1. Copy the script into a text editor and save it with no extension
# 2. Make it executable like so: chmod +x path/to/script
# 3. Run it from the Terminal in one of two ways:
#       * path/to/script ipa_path="path/to/ipa" archive_path="path/to/xcarchive"
#       * path/to/script ipa_path="path/to/ipa" toolchain_path="path/to/toolchain"
