Using Eclipse/Subversive I commanded it to delete a branch of mine. Unfortunately it also took the liberty of wiping out my trunk folder. SVN isn't my strong suit so I am trying to figure out how to get Subversive to move it's head back one revision so the trunk/branch that was deleted re-appears again. Anyone have any ideas? Thanks!
Take a look at undoing changes at the svnbook website. You're looking for a reverse merge. Something like (assuming revision 1234 was where it all went wrong)
svn merge -c -1234
