# This simple script checks for commits beginning with: scripted-diff:
# If found, looks for a script between the lines -BEGIN VERIFY SCRIPT- and
# -END VERIFY SCRIPT-. If no ending is found, it reads until the end of the
# commit message.
# The resulting script should exactly transform the previous commit into the current
# one. Any remaining diff signals an error.
