Comment (by eschnett):

 I've thought about this, and the danger is that one gets use to the "--
 purge" option, even if one accidentally mistypes the simulation name, and
 thus irrevocably deletes two months of progress. I also often find it
 useful to keep these old, wrong results around for a few iterations of
 this process, so that I can quickly see whether I'm trying something that
 I already tried before, or at which iteration I began to introduce a new
 error.

 Personally, I'm appending a numerical counter to simulation names. That
 does the trick for me, but is obviously less convenient than it should be.

 Instead of purging simulations, I suggest to rename the old simulation
 (after checking that it is inactive etc.) by appending such a numeric
 index; simulation "bbh" becomes "bbh.0000" etc. Their names should clearly
 identify them as backups, and one can easily purge them at a later time.

 What about --rename as an option for this? Or --replace?
