Replace localized data from the `source` directory with localized data from `l10n` and `extra_l10n`.
The `source` argument points to a directory containing a packaged
application (in omnijar, jar or flat form).
The `l10n` argument points to a directory containing the main localized
data (usually in the form of a language pack addon) to use to replace in the packaged application.
The `extra_l10n` argument contains a dict associating relative paths in
the source to separate directories containing localized data for them.
This can be used to point at different language pack addons for different
parts of the package application.
The `non_resources` argument gives a list of relative paths in the source
that should not be added in an omnijar in case the packaged application isin that format.
The `non_chrome` argument gives a list of file/directory patterns for
localized files that are not listed in a chrome.manifest. If `minify`, `.properties` files are minified. """
