Is there a way to "hijack" a file in subversion like there is in ClearCase. Googling so far has not given me a definitive answer. For non ClearCase users Hijacking a file means temporarily removing it from version control.
SVN operates on a "copy-modify-merge" model, meaning it's always possible to make local modifications to your working copy, without needing to "lock" or "hijack" it.
