The "push" command:

Usage: fossil push ?URL? ?options?

Push all sharable changes from the local repository to a remote
repository.  Sharable changes include public check-ins, edits to
wiki pages, tickets, and tech-notes, as well as forum content.  Use
--private to also push private branches.  Use the "configuration
push" command to push website configuration details.

If URL is not specified, then the URL from the most recent clone, push,
pull, remote-url, or sync command is used.  See "fossil help clone" for
details on the URL formats.
