A simple way to branch a small component of head in order to do work in a project branch while still using most of the parent branch. This has the effect of lessening merge events and allowing one to better integrate with the mainline branch.
Example:
- svn mkdir 'svn+ssh://svn.freebsd.org/base/user/sbruno/1394dev'
- svn copy svn+ssh://svn.freebsd.org/base/head/sys/dev/firewire svn+ssh://svn.freebsd.org/base/user/sbruno/1394dev/firewire
- svn co svn+ssh://svn.freebsd.org/base/head
- cd head
- svn switch svn+ssh://svn.freebsd.org/base/user/sbruno/1394dev/firewire sys/dev/firewire
