Oh, dear. In my quest to make URLs pretty, I think I used pathauto to batch process away all the "old" URL aliases. Of course, these old aliases need to continue to work, so that the poor internets don't become clogged with dead links. And think of the poor crocheters.

Thing is -- how can we have both? Or can we? I suppose it's possible I can't have my batch-process cake and eat it too. But regardless, the question remains: is there a handy command-line-Emma-magic that can bring back the old aliases, even if it means ditching the the pretty ones?
