Functional, but ugly, with unknown results when I switch to the next tag
[jeff@port16 wp-content/themes/twentyten]$ svn sw -r 15464 http://core.svn.wordpress.org/trunk/wp-content/themes/twentyten
Updated to revision 15464.
From the svn documentation:
In other words, if a user knows that the branch work needs to happen on only a specific subdirectory, she uses svn switch to move only that subdirectory to the branch. (Or sometimes users will switch just a single working file to the branch!) That way, the user can continue to receive normal “trunk” updates to most of her working copy, but the switched portions will remain immune (unless someone commits a change to her branch). This feature adds a whole new dimension to the concept of a “mixed working copy”—not only can working copies contain a mixture of working revisions, but they can also contain a mixture of repository locations as well.
