Introduction
It happens to everyone sooner or later: a split second after you hit Enter you realize
your mistake, but it's too late; you just deleted a valuable file or directory for
which no backup exists. Or maybe you have a backup, but it's a month old...
and in shock you see the past month flash before your eyes as you realize in pain
what you'll have to do all over again...
Fortunately, you remember that files are never really deleted, at most
overwritten by new content. So, you remount the disk read-only as fast as possible.
But now?
