# This script:
# enforces a Release build
# creates a .zip file of the application. You could also package up a .dmg with additional material.
# fetches the signing private key from the keychain. This step might pop up a dialog: 
# calculates the SHA1 checksum of the distribution file
# signs the checksum with the private key
# converts the signature to Base64
# emits an item block with all the information (date, size, version) about the update. You add this block to your appcast XML file.
# I also let it print out the scp commands required to publish the update.
