Upgrading instruction
To upgrade a previous installation of ExtFile to 1.2.0 you have to edit
file 'Config.py' and verify the repository options are to your taste.
As the defaults have changed, some options will have to be modified
to achieve 100% backward compatiblity. These are:
REPOSITORY_PATH = ['var','reposit']
REPOSITORY = FLAT (or SYNC_ZODB, whatever you had set before)
REPOSITORY_EXTENSIONS = ZOPEID
Packagers may choose to distribute a preconfigured 'Config.py' according
to their target platform's requirements.
