# 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. |
