I didn't find a solution yet, but given that there are at least two cases where this would be useful I think adding something to Kranc would be favorable over a case-by-case work-around.

I've added Before and After options to calculations which are supposed to contain strings.  Update to the latest Kranc to get this.  These will be added as " before ... " and " after ... " to the schedule point that is used, both in the manual and automatic cases.  This functionality used to be there a long time ago, when all scheduling was manual - I'm not sure why it was removed.  However, I ran into a problem with McLachlan.  There is some hacky code in the Makefile:

	perl -pi -e 's/MoL_PostStep/MoL_PseudoEvolution/g' ML_ADMQuantities*/schedule.ccl

What is this for, and can it be removed?  Since I want to schedule after MoL_PostStep, this code is obviously causing problems!
