"""
|
|
A script to migrate the offpunk cache to the newest version.
|
|
|
|
For each new version of offpunk that requires changes to the cache a migration
|
|
function should be written. The name of the function should have the format
|
|
v<major-version>_<minor-version>_<patch-version> and it should accept the
|
|
offpunk cache directory as a string. The function should perform a migration
|
|
from the immediately previous cache format. All migration functions must be
|
|
called at the end of this script from oldest to newest.
