Discussion

• I cannot check now the portability, but I believe ccperl is not found on Unix(?)
• There are cases when rmelem is the right thing to do, and even then, the sooner the better.
  • Suppose you just imported (e.g. with clearfsimport) a new version of a tool (100's of files) and you notice you did it in the wrong directory—the tool was already found somewhere else. Well, the best is to clean up what you did before anybody else may access it. Do it fast, as you still can, because if somebody has time to drop a label for instance, you won't be allowed anymore.
• rmelem is already guarded against the most glaring misuses. You can only remove something you own, and which doesn't bear labels (there used to be some darks corners there, maybe there still is...)
