<oerjan> le/rn tmp//tmp/ is a directory for files that are not worth saving in HackEgo history, but which should still survive a single command. Note that it interacts funnily with HackEgo\'s lock and re-run commit check: files can disappear if you don\'t know what you\'re doing. Basically, don\'t modify files inside and outside tmp/ in the same HackEgo command.
