Package Updater Matrix

Import Behavior for import and package types

once

import package if it hasn't been imported already

never

skip the package

import

import package regardless of whether it's been imported already

Preserve-Local

Packages can also be marked preserve-local=false. Unmarked packages assume preserve-local=true. This governs behavior after the above matrix has decided to actually import the package. By default, any pages with locally modified content will not be overwritten even if the package itself proceeds to import. With preserve-local=false, local changes will be overwritten.
