Create a local version of a given feed. This is useful to: - Test modifications to a feed locally, without having to publish them. - Override the implementation for a public feed with your own sources. Usage: 0local feed.xml Creates feed-local.xml in the current directory (overwriting it if present). This local feed will have only one (local) implementation, with path "." You can also pass in a URL instead of a filename, to make a local version of the feed at that URL. To register (or unregister) your local feed as the preferred implementation for the feed URI, run: 0launch -f feed-local.xml And follow the prompts.
