Now the CopyMove extension uses subversion, and you can check it out from its repository with:
svn co http://dev.gravityblast.com/svn/projects/radiant/extensions/copy_move/
Thanks to Benny Degezelle now it works with the shards extension. This is the best way to hack the Radiant admin UI! Benny also helped me updating the rake tasks and rewriting the CopyMove html structure so it is similar to the other admin screens…Thanks Benny I also moved all the code in a separated controller, wrote a complete test suite, and added the ability to choose the status for the copied pages.
